Mountains + Lymbyc Systym

As Mountains, Brendon Anderegg and Koen Holtkamp play droning ambient songs that sound like nothing or everything, depending on a listener’s disposition. The music is mushy and meditative, like a Rothko painting—or is it haphazard and meaningless, like a radiator hiss? Tonight, the band plays as part of the Brooklyn Book Festival "Bookends" Series.
