Chris Parrello + John Shannon

Jazzers-turned-singer-songwriters come together for this swoonsome bill. In the headline slot, Chris Parrello fuses beguiling, shuffly beats and cooed vocals; opening up, Pittsburgh's John Shannon makes beautiful, minimalistic compositions based around the guitar and upright bass—to which he matches his delicate, wafting voice. It's the musical equivalent of staring out at a very still, very lovely lake.
