Joe Lally was onstage, playing at full throttle, when he realized that his band had found a true kindred spirit. It was the fall of 2021 and the Messthetics — the instrumental trio of Lally on bass, his former Fugazi bandmate Brendan Canty on drums and guitarist Anthony Pirog — were at Brooklyn venue the Bell House, digging into their up-tempo riff workout “Serpent Tongue.” Joining them for the piece was a special guest, acclaimed jazz saxophonist James Brandon Lewis, making only his second cameo with the group after a drop-in at another New York show back in 2019 and pushing their song like crazy! That imperative — the sense that there was more to explore within what began as an ad hoc union among the four musicians — lingered after the performance ended. Now, Lewis, Pirog, Lally and Canty are ready to unveil their first full-length album as a quartet. Across the album, due out on March 15th via the legendary Impulse! label, the quartet can be heard locking into a hard, swaggering funk groove on “That Thang,” cradling a wistful, jazz-like theme on “Asthenia” or rocketing into ecstatic art-punk overdrive on “Emergence.” Judging by the enthusiastic response the Messthetics and their esteemed guest have received during more recent live meetings, listeners are similarly eager to hear what happens when brilliant players like these stretch themselves through collaboration. “I feel like, more and more, there’s an audience for exploration,” Canty says. “And I really hope this record’s part of that.”
