Mariah Carey, Jane's Addiction and a reunited TLC are among the artists who will help MTV blow out the candles at a bash celebrating the network's 20th birthday.

MTV's "Live and Almost Legal" concert will take place August 1 at New York's Hammerstein Ballroom and will feature live performances from the above artists as well as Run-DMC, Billy Idol, Method Man, Mary J. Blige, Sum41, Busta Rhymes and the Neptunes, according to a network spokesperson. Tour footage from big-ticket summer concerts — including shows by Bon Jovi, Blink-182, Nelly, Depeche Mode, Aerosmith and Sugar Ray — will augment the onstage action.

"TRL"'s Carson Daly and other MTV on-air talent will host the event, which also promises the return of animated angst-ridden adolescents Beavis and Butt-head and appearances by VJs past, including the original five who introduced the world to the music network: Martha Quinn, JJ Jackson, Alan Hunter, Nina Blackwood and Mark Goodman.

The three-hour special will air live on MTV and MTV2 at 8 p.m. ET, and tape-delayed at 8 p.m. PT.

Prior to the broadcast, MTV will present "MTV20: Buggles to Bizkit," a 12-hour special featuring groundbreaking videos from the past two decades. Clips slated to air include Duran Duran's "Hungry Like the Wolf," Peter Gabriel's "Sledgehammer," Nirvana's "Smells Like Teen Spirit," Weezer's "Buddy Holly" and, of course, the Buggles' "Video Killed the Radio Star," MTV's first video, which aired at 12:01 a.m. on August 1, 1981.
