Tortoise

Despite being one of post-rock's most foundational acts, Chicago experimentalists Tortoise have always demonstrated a penchant for stepping outside the genre's strictures, winding between electronica and improvisational jazz in its eclectic 10-minute epics. With its first album in nearly seven years, The Catastrophist, the group veers toward those latter influences, having developed the tunes from a project commissioned by the City of Chicago exemplifying its ties to the city's jazz scene.
