Molly Hamilton and Robert Earl Thomas have been bringing nature to life as Widowspeak with their yearning, nostalgia-laced jams for a while now, so it seems fitting that they perform outdoors in MoMA’s sculpture garden tonight. Regular museum admission grants listeners access to the special performance, which is held in conjunction with the MoMa Nights and PopRally series. After forming the band in 2010, Hamilton and Thomas released Almanac in early 2013 through the obscurity-loving Brooklyn label Captured Tracks. Their music leans on Americana until it breaks, then glues it all back together with pieces of psych rock and heady, delicate guitar work. Their latest record, The Swamps, highlights Hamilton’s gossamer croons with increased percussion and even more off-kilter rhythms, channeling the murkiness that the album’s title suggests. This intimate, novel venue lends itself to a unique performance not to be missed.
