One of the few live music venues east of the hills just opened under new management. But it looks like the new owner of Concord’s Bourbon Street won’t be booking nearly as many young bands as before. So far, the club has regularly scheduled classic rock, salsa, country, DJ (’80s music), and comedy nights. Clearly, the new owner is looking to attract older, professional types looking for a night away from the kids. Monetarily, it makes sense, but frankly, it makes us a little sad.
