The Deep Dark Woods hail from Saskatoon, where frozen nights can make a day feel like a year, and they’ve channeled that icy inspiration into a cozy roots-prairie-goth sound. On Nov. 28, the band helps Phil Lesh kick off a two-week extravaganza to celebrate the debut of the Grate Room at Terrapin Crossroads. Moreover, it’s free! (Tickets for the rest of the fortnight’s shows run up to $150.) The spankin’ new Grate Room boasts a world-class sound system and promises to be a diverse venue with trivia nights, big-band and salsa dance nights and, of course, tons of live music. Get there early, because Dead fans will be lining up at the door on Wednesday, Nov. 28, at Terrapin Crossroads. 100 Yacht Club Drive, San Rafael. 8:30pm. Free. 415.524.2773.
