Is that a jet engine or a some crazy guitar distortion you're hearing? Probably both. This indie rock landmark by the airport spotlights local comers and national touring bands trying to break into the bigs. The dive only holds a couple of hundred, so check the schedule in advance for tickets—hot acts sell out in a flash. Nirvana, Arcade Fire, and Vampire Weekend have all rocked the Casbah during its 25 year history. Every night of the week you'll find live music at this hipster haunt, typically a double or triple bill, and for most shows, a ten spot gets you in the door. Between bands you can play pool, retreat into a small (but often smoky) courtyard, or take advantage of the better-than-expected beer options.
