Pittsburgh indie-punks Calyx have two EPs and a single dating back to 2015, but now they're finally ready to release their first full-length, Stay Gone, and judging by lead single "Leslie Plain and Strong," it's shaping up to be the best thing they've done yet.

Compared to the scrappy, lo-fi earlier recordings, this new song (recorded and mixed by The Superweaks' Evan Bernard) is crisp and loud, and the band's playing is tighter than ever. The song is stuffed with catchy, fiery indie-punk hooks, and when the gang vocals -- which include Chris Diehm (Thin Lips, 1994!, etc) and Melissa Brain (Amanda X, Bad Heaven Ltd) -- come in, Calyx sound like they're gonna explode.
