LFO, B*Witched Head Nickelodeon's All That Festival

LFO, B* B*Witched, Blaque, Hoku, and No Authority are among the acts who will appear at this year's Nickelodeon All That Music & More Festival, a tour launched last year by the cable network. Nickelodeon is owned by Viacom, which counts MTV and VH1 among its properties.

The tour opens in Southern California on June 29 and runs through early September. It will play at amphitheaters, arenas, amusement parks and major fairs. Seven acts will be on the bill in each city.

Last year's All That event featured multiple musical stages as well as exhibit areas, autograph signings, promotional tents and play areas. Between acts, the festival features skits featuring stars from Nickelodeon's live-action television series "All That."

This year's festival will be hosted by "All That" stars Nick Cannon and Kenan Thompson. Non-musical events will include auditions for "All That" and "Double Dare 2000," another Nickelodeon program.
