With their sputtering beats and trotting guitars, Northampton, Massachussetts indie funk quartet Mammal Dap powerfully reminds the listener that instruments alone can be deeply affecting. Excluding a human voice, songs like the drum-skipped "Ariel" and the bass-rubbed "Tried Tides" (streaming below) evoke autumnal melancholy while ultimately letting summer joy slide through. A compelling combination of Ratatat's elasticity and Flying Lotus's claustrophobia, such subtle yet fierce tracks play along to an intriguingly unpredictable pace. Mammal Dap has many forthcoming shows listed, including one this Thursday (12/10) at Stomping Ground in Putnam, CT. - Zach Weg
