You read that headline correctly—D.C. experimental rockers Buildings have assembled a guitar orchestra for their spot tomorrow opening for Rhode Island noiseniks Lightning Bolt at DC9.

Collin Crowe, a guitarist in Buildings who organized tomorrow’s orchestral project, says 15 guitars will be on stage. “I hit up mostly friends of mine for it,” he says. “To me, there’s a lot of us not doing very much.”

Crowe, who composed music for the orchestra, says he’s “freaking out a bit” about the ensemble’s inaugural performance. He says expect an ambitious piece that’s “going to be really soft and chilling.”

The band had toyed with the idea of a guitar orchestra before. “It’s something I’ve always wanted to do, but never had the incentive to do it,” Crowe says. “Being invited to play with Lightning Bolt was that incentive.”

Rehearsing with large ensemble was “kind of cool,” Crowe says. “It [felt] like a party every time.”

As for the venue, whose second-floor space often vibrates during gigs? The employee who picked up the phone at DC9 this afternoon put it plainly: “Fifteen guitars? Oh man. Jeez.”
