Jackson's tour organizer Live Nation has said she will not be making up the shows in Montreal; Boston; Philadelphia; Greensboro, North Carolina; Fort Lauderdale, Florida; Uncasville, Connecticut; and Verona, New York she was forced to cancel last month, because of sudden onset migraine-associated vertigo. She did manage to perform makeup dates in New York City and Atlanta.

There's no word yet on when or how fans will be able to seek a ticket refund for the nixed shows.

Despite canceling nine shows on her Rock Witchu Tour due to vestibular migraines, Janet was present and full of energy for her Saturday performance at Madison Square Garden. She left the packed house standing and cheering for more when she closed with her top-five hit "Runaway," but received mixed reactions throughout the night to tracks from her latest album, Discipline.

Although the LP is Janet's least successful album to date (as of September, record sales stood at 415,000 copies in the U.S.), the turnout at Madison Square Garden probably convinced Midtown onlookers otherwise. Hundreds of Janet fans of all ages and backgrounds spilled onto the streets, clutching merchandise and congregating outside the venue as if unwilling to leave, still glowing and chattering excitedly about the show they had just experienced. "Did you see her dancing the entire time?" shouted a middle-age mother to her group of friends, teenage daughters in tow. "It was flawless!" Other fans expressed similar sentiments. "Oh my God, that was hot," a male teen crowed to his similarly well-coiffed associates. “Janet is timeless, right?" Responses to the new album, however, were decidedly mixed. Words used by the crowd to describe her latest release ranged from "pretty good, but not great" to "disappointing."

Janet may have some work to do if she wants to remain relevant to existing fans and the latest generation of pop aficionados. A mother-and-daughter duo sitting in front of me seemed mixed in their judgment of the night's performance. The daughter was more interested in texting friends than watching Janet perform, rarely looking up as her mother swayed and sang along to old favorites. Even when Janet performed tracks from Discipline, the daughter was busy browsing her MySpace page, asking her mother mid-song, "Can we go yet?"

Even die-hard fans didn't seem committed to the new album. Although they stood through her hits from janet. and The Velvet Rope, most of the crowd sat down and conversed during her new singles, seemingly anxious for her to get back to the older songs.

Speaking with several long-term fans who have seen all of her tours, I realized that there's definitely nostalgia for Janet's past and a desire for her to grow as an artist. Tony,* a thirtysomething New Yorker, began following her tours as a teenager, normally attending five to 10 shows per outing. He admitted that this is the first show he has caught for Rock Witchu — he simply hasn't been that interested.

"It's just not the same any more," he explained. "Janet has always stuck with the same routine for all of her tours, but at least the music was hot. The music lately isn't that great anymore, and she doesn't mix anything up in her shows."

Tony caught a concert on Madonna's Hard Candy tour last month, and, despite acknowledging that Janet is still the better dancer, admitted that "Madonna is still hot because she is always changing — her sound, her look; it's never the same. If Janet wants to keep her fans and get new ones, she is going to have to step out of her box more. Discipline sounds just like her old stuff — but not as good. People are expecting more from artists nowadays, the old way of doing things is over."

Two weeks of concert cancellations ended last night in Washington, D.C., when Janet Jackson returned to the stage at the Verizon Center to resume her tour, which was sidelined by a mystery illness that's now been identified as vertigo. According to The Associated Press, Jackson, sporting a Mohawk, charged the stage amid fireworks and clouds of smoke, playing a bevy of her earliest hits, like "Pleasure Principle" and "What Have You Done for Me Lately."

"It feels so good to be back after being down just a little bit," Jackson told the crowd, during what ended up being a two-hour set. The AP reports that the pop singer did look winded at times, and at one point, paused to admire her backup dancers.

At the conclusion of her set, Jackson, with tears in her eyes, told the crowd, "I love you, D.C., so much." Her manager said the singer is feeling well enough to continue her first North American run in seven years. She has shows scheduled in the coming weeks in Atlanta, Houston, Dallas, New York and East Rutherford, New Jersey.

Meanwhile, ABC News has speculated that perhaps it's not illness but a non-medical ailment that's plaguing Jackson: poor ticket sales.

I have been a fan of Janet Jackson since I was about 5 years old. I have attended every tour since Rhythm Nation, and I own every album she has released. When the opportunity presented itself to cover the Janet Jackson Rock Witchu Tour concert at the Staples Center in Los Angeles last night, I quickly recruited myself.

(See video of Janet Jackson performing "Pleasure Principle" after the jump.)

At the show, I bought the Janet Rock Witchu Tour booklet, which recounts a day in Janet's life on tour through photos and a schedule. For the sake of comparison, here's a little rundown of her day (per the book) and my own, leading up to the amazing moment when the two coincide:

9:30 a.m.: Janet wakes up and snuggles with her dog, who appears to be a puppy. He is a boxer.

Meanwhile ... My flight from New York left this morning at 6:00 a.m., and I am just landing in Los Angeles. I immediately turn my Blackberry on to a host of e-mails from Janet's management and our team in the East Coast office, regarding our coverage of the tour.

10:00: Janet smiles as she is served coffee in bed.

Meanwhile ... I am at the Hertz counter getting my rental vehicle while juggling phone calls and e-mails on my Blackberry. I speak with Yasmine Richards, the producer of this piece, and we set up a lunch meeting.

12:00 p.m.: Janet has a meal prepared for her by her chef and staff. Still lounging in her all-white pajamas and a long, elegant white robe, she joins a couple of business associates in a sitting area, and they go over sketches and look at product samples of her new lingerie line.

Meanwhile ... Yasmine and I meet at Grande Lux for lunch and discuss the plan for the evening's coverage.

1:00: Janet stands in front of a mirror in a large, luxurious closet and holds an elegant necklace to her neck. She has a unique centerpiece on her dresser that she also uses as a jewelry holder. It's a Best Choreography in a Video Moonman for "Rhythm Nation."

Meanwhile ... I'm headed down the palm-tree lined streets of L.A. to my hotel, when Gil Duldulao (Janet's friend and choreographer) pulls up next to me at a stop light in a black Mercedes Benz, texting on his Blackberry.

3:30: Janet arrives at the concert venue, dressed casually but, in true superstar form, wearing a hat low on her forehead and her large dark sunglasses that cover most her gorgeous face. She flashes her iconic smile and waves to the fans who have been waiting at the door for her arrival and are now snapping pictures with their cameras and cell phones.

Meanwhile ... I make phone calls and respond to e-mails in my hotel room in preparation for tonight's concert coverage.

6:30: After her hair and makeup prep, stretches and a warm-up, Janet joins the band for sound check.

Meanwhile ... Yasmine and field producer James Lacsina arrive at the Staples Center for media check-in.

7:00: Janet does a vocal warm-up backstage.

Meanwhile ... Doors open to the public, and our crew is escorted through the press gate. I head to gate M4, where guests with a meet-and-greet pass are instructed to gather. It appears that most of the other guests there are business associates, sponsors and friends of Janet.

8:00: Janet begins her meet-and-greet.

Meanwhile ... A man who says he works for Janet escorts us backstage. We can hear the crowd go wild as LL Cool J begins to open the show. As we approach two dark curtains, Jimmy Jam (Janet's longtime producer and friend) emerges from behind them after visiting Janet. It is now evident to me that I will be meeting Janet shortly, and my nerves hit an all-time high. I have been around Janet several times before (one of the perks of working at MTV), but I have never spoken to her, because I didn't feel it was ever appropriate. My time has come.

8:15: Janet and I meet! Our encounter with Janet is brief but absolutely memorable. I'm wearing a neck chain that has two rhinestone-encrusted handcuffs that dangle below my chest, and Janet immediately reaches for them and holds them in her hands. "I like these," she says as she looks at me with her big eyes and a smile. I smile back at Janet and tell her that I wore them especially for her because of the song "Discipline," which would later be performed at the concert. We pose for a picture, and I tell her it was a pleasure to meet her. Just as soon as it came, my meeting with Janet is over.

As I find my seat in section 115, I'm among a host of Janet's family and friends, including her brother Jermaine and sister LaToya. Former Destiny's Child member Michelle Williams and rap legend MC Lyte are inches away from me, as we all patiently wait for the show to begin.

9:00: The arena goes dark, and the nearly sold-out crowd erupts to the sounds of Janet's voice as it fills the room. The L shaped runway stage lights up, and Janet comes out from between two large letter J's center stage. In a futuristic costume, complete with a cape, she performs her hit "Pleasure Principle," solo. It's not until she performs her second song, "Control," that 13 dancers join her, emerging from underground in various positions around the massive stage. For two hours, they perform nearly 40 hits spanning this pop icon's career, complete with theatrics, costume changes and a few surprises.

But I won't divulge too much (you can check out the clip below for a sneak peek!), but if you want to Rock With Janet, you have to come see this show yourself. Janet never disappoints, and the Rock Witchu Tour is testament that after over 20 years in the industry, she's still got it!

With D-Nice spinning -- "Put On," by Young Jeezy and Kanye West, T-Pain and Lil' Wayne's "Can't Believe It," and Game and 50 Cent's "This is How We Do," all were huge for the dance floor -- D stood at the booth hyping up the party. Nice played the remix to Dru Hill's "Sleeping in My Bed," while Dupri shouted, "Brat I love you!"
