The Chilean band Föllakzoid specialize in the pillowy sort of rock music designed to shield you from the world for a while. Huge, looping riffs stretch across deeply repetitive percussion, creating an atmosphere somewhere between trance and stupor. The word "psychedelic" is never far away when reading descriptions of the band, but three albums into their career, they’ve explored many colors on that particular spectrum. Beginning with outward-facing, Josh Homme-indebted rock on their eponymous debut in 2009, they switched to something closer to krautrock on 2013’s II. Here, they tighten their sound, cutting out the meandering themes and occasionally sloppy riffing. There are only four songs, but extra details emerge slowly on repeat listening.
