A collaboration between 33-year old former Battles leader Tyondai Braxton and 75-year old minimalist forefather Philip Glass takes place today at the All Tomorrow's Parties festival. It hardly falls under the header of WTF. In fact, it likely would have only taken a few dozen monkeys with a few dozen festivals to curate to figure out the pairing. And, in fact, many of the acts that have graced ATP's post-rock stages over the years--including Tortoise, the first show ATP founder Barry Hogan promoted--owe plenty to Glass. But that doesn't make this year's pairing any less intriguing. Braxton has mostly lain low since 2009's mammoth Central Market, a rich mind bender with the Wordless Music Orchestra, give or take other commissions from Bang On A Can and Alarm Will Sound. Along with the New York debut of Sonic Youth's Lee Ranaldo Hanging Guitar piece, the Braxton/Glass collaboration holds down the experimental corner of this eclectic bill.
