Formed in 2016 by four friends with minimal experience as musicians, Bacchae make music with no assumptions about what a punk band should sound like. On their new LP, “Pleasure Vision”, brooding synth-driven pop sits alongside prickly, fast-paced punk and spooky post-punk sounds. Sometimes you get all of that in a single song. But whether the band is exploring the pain of a doomed relationship or the push and pull of disgust and desire while shopping online, what carries through it all is a sense of uncertainty, dissolution and dread.
