Editor's Note: It's summer concert szn, which means we're all getting more bang for our live music buck as touring packages start rolling into town. One of the co-headlining tours we are particularly excited about hit Cambridge's Sonia this past Saturday (June 29), courtesy of SiriusXM's Alt Nation "Advanced Placement" tour. It delivered Los Angeles rock trio Warbly Jets and Kansas City indie band Hembree to Central Square. Unfortunately, UK upstarts BLOXX dropped off the tour just as it hit our city, but the sheer volume of awesome songs on display (check Warbly Jets' "Propaganda" and Hembree's "Culture" for a primer) made sure it was a fun Saturday night out in the city. Vanyaland's John Hutchings was inside and all over Sonia capturing snaps of the action, and you can scan through his full gallery below.
