Two members of East Village royalty, Philip Glass and Iggy Pop, have upcoming gigs at venues that befit their majesty. Iggy, whose throne is in Miami these days, just released the first and second songs off of Post Pop Depression, his recently announced album with Josh Homme of Queens of the Stone Age (out March 18). The supergroup (also made up of members of The Dead Weather and Arctic Monkeys) announced tour dates today. The NYC stop, on April 12, will be at the United Palace Theatre, the gilded, grandiose former movie palace in Washington Heights. (The onetime Loews “wonder theater” was a sister of the Kings Theatre in Flatbush, and is bigger and possibly even more jaw-dropping than its lavish sibling.) Tickets go on sale Saturday at 10 a.m., with presales starting Thursday.
