The unauthorized, fan-loathed Michael Forever tribute concert in Wales continues to stockpile A-list talent... never mind, they just added La Toya Jackson. The black sheep of the Jackson clan revealed yesterday that she'll join Christina Aguilera, Cee Lo Green, and the Black Eyed Peas at the October 8th show. The BBC writes that La Toya will "step out of retirement after 20 years" to perform at Michael Forever, but she released new music both in 2004 and earlier this summer, so it's unclear what two-decade hiatus they're referring to. Maybe she hasn't performed live in 20 years? If that's the case, it's safe to say she was not missed.

The main reason Michael Forever has created a rift in the Jackson family -- other than it not being authorized by the Jackson estate -- is because it conflicts with the ongoing manslaughter trial of Dr. Conrad Murray, Michael's personal physician. Nearly every member of the Jackson family has attended the proceedings since they began earlier this week,

Sylvia Robinson passed away today from congestive heart failure at age 75. Some music fans known her as one-half of Mickey & Sylvia, whose 1956 hit "Love Is Strange" appeared on the blockbuster soundtrack to Dirty Dancing in 1987. Others known her as the vocalist behind the 1973 soul anthem "Pillow Talk." And legions have reaped the benefits of the risks she took as a record label boss -- Robinson, as co-founder of Sugar Hill Records, was the driving creative force behind what's widely considered to be the first hip-hop song ever: the Sugarhill Gang's "Rapper's Delight." One of her other landmark successes was a little song known as "The Message" by Grandmaster Flash & the Furious Five. No wonder Robinson was known as the Mother of Hip-Hop. A quick glance back at how she shifted our culture: 

It's been over a month since Yahoo! premiered the trailer for Martin Scorsese's upcoming documentary George Harrison: Living in the Material World, and with less than a week to go before the film's HBO premiere, we have another early look -- a clip in which Paul McCartney explains how Harrison wound up in the Beatles in the first place. Even if you know the Fab Four's story backwards and forwards, it's awesome to watch Sir Paul recount how this guy who was "a bit young" made his way into arguably the band that changed everything.

Remember: The two-part doc will debut on HBO October 5th and 6th before getting DVD and Blu-ray releases on October 10th. It features new interviews with McCartney and Ringo Starr, as well as Eric Clapton, George Martin, Yoko Ono, Tom Petty, and Phil Spector. And it looks really, really good.

Just after midnight, probably right around when Radiohead were playing the final notes of "Street Spirit (Fade Out)," T.I. walked out the front doors of an Atlanta halfway house as a free man after completing his 11-month prison sentence. This time, there was no luxury party bus to whisk him away, no entourage members or business managers or VH1 producers to greet him at the exit. He simply stepped into a chauffeured SUV alone and rejoined society, TMZ reports.

It won't be long before Tip explodes back into the music scene: According to MTV, T.I.'s next single, a collaboration with producer DJ Drama and rapper Big K.R.I.T., is already ready to go. The track was actually supposed to arrive this past Monday, but they probably decided to save it until T.I. was free. Now you'll have something to listen to while you read Tip's first novel.
