With current-day experimental electronic music so often divided along trendy blog lines, it's refreshing to hear a local act resurrect a term you don't hear too much on Hype Machine and the like — trip-hop. But the local three-piece Astrea Corporation does, indeed, pick up a strain of boom-bap beats and wrap it in all kinds of lush but electronic beats. It updates that '90s sound with contemporary left-field flourishes, though, from looping, echoing vocals to the occasional warped bass line and drum 'n' bass inflection. On some tracks, like the meandering, almost yodelly "Artifact A," they even get positively New Agey.
