Chicago’s Tortoise is interviewed.
More than any other band, the veteran Chicago group has most singularly been associated with the largely instrumental, ’90s-born genre that incorporates all kinds of non-rock sounds yet most appealed to an indie-rock audience. The band’s latest album, “Beacons of Ancestorship,” is one of the most vigorous of its career, but still has some of the jazzy and ambient touches that made albums such as “Millions Now Living Will Never Die” and “TNT” enduring favorites. Herndon also plays in a large handful of avant-garde bands — Exploding Star Orchestra with Rob Mazurek, Powerhouse Sound with Ken Vandermark and A Fox Can Be Hungry with fellow Chicagoans — and explains why foreigners are more open to out-there sounds than Americans. Tortoise plays at the Black Cat on Sunday.
