After doing time in other bands, Susil Sharma (vocals, guitar and synths) recorded the noisy, melodic demos that would become the original basis for the Montreal rock trio Heat, eventually joined by Matthew Fiorentino (guitar and synths) and Raphaël Bussières (bass). Their debut EP, Rooms (stream it below), arrived in 2014 and was rereleased the following year, earning the band comparisons to Pavement and the Jesus and Mary Chain. Taking a sonic leap forward, Heat (above, a video for “Lush”) returned with their debut full-length, Overnight (stream it below)—“heavy on melody and hooks, but with brash, shadowy undertones,” according to AllMusic—in January. And they play Mercury Lounge tomorrow night. NYC pop quintet Navy Gangs open the show.
