Forestears is a band in Brighton with at least one pun in its name and music that moves from major to minor and back with verve, borne along by some riveting vocalists, a horn section that’s especially noteworthy, and very solid drums and guitars. From this young six-piece (formed in 2009), which has already released a third EP, Against the Floor, I’m hoping to hear much more of its music, full of joy even when it’s dark.
