Right now I've got tickets to see the Klezmatics (3/13), Xiu Xiu (4/10 - mainly going because I think their drummer is awesome), the Boston Symphony Orchestra (4/17), Bettye Lavette (4/30)... and I'm hoping to make it down to NYC in June for some shows at the Stone, a favorite duo of mine is curating that month and there are a ton of good concerts scheduled. Most likely I will come down the last weekend in June to see Mephista, Masada String Trio, and I hear rumors of a Cubanos Postizos show that week as well, in which case I'll stay for that too.
I might be going to a concert at the Boston Jewish Music Festival tomorrow, a band I really like (Golem) is playing, but the tickets are so expensive I haven't decided whether or not it is worth it.
I wanted to see Peter Gabriel at Radio City Music Hall but I got confused about the release date of the CD and the sale date of tickets and by the time I realized, it was sold out

Wish I were seeing Joe Henry on his current tour but he's not coming to Boston. If I were in NYC I'd be hitting his late show Monday night at Blue Note, there'll be a special guest guitarist...
