This long-running project fronted by the indispensable Bryan Murphy has had a busy month putting on blow-out album release parties up and down the coast for their newest EP, “Keep Your Hands Busy Vol. 1” (the Boston edition went down this past Wednesday night at Brighton Music Hall). The record, the first half of a promised two-part collection, lays out a tense game plan of turn-on-a-dime-guitars and acrobatic vocal harmonies — like the Cars following a malfunctioning GPS.
