Meditate on the metaphysical with Active Child this Thursday at the Firebird. Pat Grossi combines ethereal falsettos and swelling harmonies with billowing harp that floats over an electronic horizon. Deer Tick is four albums deep into its catalogue, and now come with David Letterman's approval. The band makes rock n' roll that could comfortably tread over a dirt path. See them at The Firebird on Wednesday. Shows are happening elsewhere this week as well; check a few of them out below.
