Friday afternoon turned out to be fine concert weather, with high clouds dulling the sun's edge and a cool lake breeze occasionally refreshing weary fans. But don't tell Mark Foster, hapless leader of L.A.'s Foster the People, whose crisp white dress shirt was transparent with sweat by the band's third song.
Foster the People are brand new, riding a slick slacker single from last year that landed them on one of Lollapalooza's biggest stage this year. They're still exploring who they are as a band, and they played the day's most eclectic set -- evolving from dreamy, keyboard-laden grooves to ill-advised R&B to throwaway love ditties and, near the end, a straight cover of Neil Young's "Heart of Gold." Foster is an odd duck, singing in his pinched nasal voice and occasionally leaping over to mash piano keys or pound the drums (as he did during "Call It What You Want"). Sometimes he was ridiculous, his shoulders jerking up and down as he whined his New Radicals funk-lite; other times he was gloriously unhinged, cackling like a madman near the end of the set when Foster the People suddenly turned into a garage band (or Joe "King" Carrasco). I the end they returned to what they thus far do best, laying down supple, sleepy grooves for that aforementioned single, "Pumped Up Kicks." Most of the crowd was pumped up and sang along.
