Alice in Chains, Deftones and Mastodon are touring together this fall, on a trek dubbed "Black Diamond Skye" (the name is composed of one word from each band's most recent album). According to the tour's official website, there is a St. Louis date already scheduled: October 1 at the Scottrade Center. Tickets on sale soon. AIC played at the Pageant in February, while Mastodon invaded last year. Deftones is finally releasing the long-awaited album, Diamond Eyes, next Tuesday.
