For all the tales of bands that stumbled prematurely into overwhelming onslaughts of publicity and promotion thanks to the turbocharged buzz cycle of the Internet, the story of Unknown Mortal Orchestra is a fortunate foil. Indeed, in the last three years, UMO has gone from a mysterious band with one uncredited song online to a fully formed act that released its second album of eccentric soul on one of the best indie labels of the land. Issued by Jagjaguwar in February, II delivers less of the instantaneous hooks than its self-titled predecessor. But its restraint and mood supplant the need for immediacy. The music feels like the glow of a springtime Saturday spent lost with a stack of records and a few friends, all caught in a haze too pleasant to leave. Even at its bass-thump busiest, II feels unplugged and preternaturally at ease, bleary eyes directed forever to the distance.
