The upcoming Queens Of The Stone Age/...And You Will Know Us By The Trail Of Dead tour has doubled in size, with dates now booked through Oct. 1 in Denver. As previously reported, the trek will begin Aug. 30 in Washington, D.C. Additional West Coast dates will be added in the coming days; a third act is expected to join the bill.

Foo Fighters frontman Dave Grohl will not be drumming for Queens on the shows and will play his final show with the band Sunday (July 28) at the Fuji Rock Festival in Japan. Queens bassist Nick Oliveri told Billboard.com the group had a few candidates in mind to replace Grohl but no official announcement has yet been made. As on a spring North American club tour, A Perfect Circle's Troy Van Leeuwen will play guitar and former Screaming Trees frontman Mark Lanegan will sing a few tunes.

Queens' next Interscope record, "Songs for the Deaf," is due Aug. 27 and will be preceded by the single "No One Knows." A video was recently shot with director Michel Gondry and is due to begin airing in early August on video outlets. Trail Of Dead is touring behind its Interscope debut, "Source Tags & Codes," which hit No. 17 on Billboard's Heatseekers chart and has sold 65,000 copies in the U.S., according to SoundScan.
