VH1 is preparing to announce two multi-artist tours, Billboard.biz has learned. The first is based on the cable music channel's annual Hip Hop Honors awards show, which debuted in 2004. The inaugural edition of the Hip Hop Honors tour will feature the Roots and still-to-be-announced special guests.

Ironically, the Roots have never been honorees of the awards show, but have acted as the event's house band. The tour will cover 15 markets, kicking off Sept. 13 in San Francisco and wrapping Oct. 5 at New York's Nokia Theatre, just prior to the third edition of the awards.

VH1 is also about to unveil its second You Oughta Know tour, featuring acts that the channel has previously deemed You Oughta Know artists. Following closely on the heels of the first YOK tour -- which took place this past spring and was headlined by Mat Kearney, with special guests the Feeling and Rocco DeLuca & the Burden -- this second version sees a couple of VH1's female YOK artists taking charge.

The 32-market run will be led by Brandi Carlile with new buzz band A Fine Frenzy (aka Alison Sudol) in the opening slot. The tour launches Sept. 6 in Eugene, Ore. A ticket presale for both tours starts July 11 at tours.vh1.com. The general public on-sale date is July 13.
