Active Child, a.k.a. multi-instrumentalist Pat Grossi, is a former choir boy from Philadelphia. His parochial influences are blatant on his delightful first EP, 2010's Curtis Lane. (Lane is the second Active Child release this year; the first was a too-hip, limited-edition cassette, Sun Rooms.) Grossi's seraphic vox ooze over cavernous synthpop and beatific harp on "I'm in Your Church at Night" (told you he was a choir boy), while the haunting austerity of "Wilderness" showcases sonic depth. Grossi has spent the last few months on tour with Islands and School of Seven Bells, but he's doing a handful of headlining dates — including this solo stop, his second St. Louis date in 2010.
