Though they hail from the UK, Glass Animals thrive in hot, humid environs. The Oxford outfit’s 2014 debut feels like a late-night rainforest cruise into uncharted territory, powered by tropical grooves and ayahuasca-induced weirdness. Even as he guides you through the drum-circle ceremony of “Walla Walla” and jungle rumble of “Pools,” singer David Bayley remains a smooth tour operator, countering the percussive propulsion with a cool, melodic sensibility that’s equal parts James Blake and Thom Yorke.
