Pop acts Hoku, B*Witched, LFO and Blaque will highlight this summer's Nickelodeon All That Music & More Festival.

The outing will hit 40 cities starting June 29 in San Bernardino, Calif., and ending Sept. 3 in Saratoga, N.Y. Boy band No Authority also will be aboard for the trek, which the cable channel says will feature at least seven acts in each city. (Sonicnet's parent company, Viacom, also owns Nickelodeon.)

With newcomers dominating the bill, Irish pop group B*Witched qualify as the tour's seasoned veterans, having released their second album, Awake and Breathe, in October. The group's four singers co-wrote all of the album's songs, including the single "Jesse Hold On."

Pop trio LFO will join the tour refreshed from a short break following months of roadwork, including a string of dates opening for teen queen Britney Spears. LFO recently released "I Don't Want to Kiss You Goodnight" (RealAudio excerpt), the third single from their self-titled 1999 debut.

Hawaiian-born singer Hoku, 17, recently broke onto the pop charts with her single "Another Dumb Blonde" (RealAudio excerpt), from her self-titled debut album, due May 2. Her latest single is "How Do I Feel."

R&B group Blaque are #32 on the Billboard Hot 100 singles charts with "Bring It All to Me," featuring 'N Sync. The song appears on Blaque's self-titled debut album (1999).

The group, whose name stands for "Believing in Life and Achieving a Quest for Unity in Everything," is the brainchild of TLC rapper Lisa "Left Eye" Lopes.

Nick Cannon and Kenan Thompson, stars of Nickelodeon's "All That" sketch-comedy show, will return as the festival's hosts.
