Ahleuchatistas is an instrumental prog punk band that formed in 2002. They play music that is meticulously thru-composed and relentlessly paced from beginning to end, morphing through perpetually evolving subtle variations, unfolding melodies that are simultaneously angular and organic. The current lineup is Shane Parish on guitar, Trevor Dunn on bass, and Danny Piechocki on drums. Their 9th studio album, Expansion, was released on October 22, 2022 on Trevor Dunn’s Riverworm Records.
