With new album Pumps, Brooklyn-based avant-electronic outfit Growing is the closest it's ever been to making straight-ahead club tracks. Since their last record, 2008's All the Way, they've expanded to a trio with new member Sadie Laska, also of IUD and Extreme Violence, who lends samples, electronics, and chopped-up vocals to these celestial jammers. The watery guitar parts of All the Way remain, rolled up into gritty, more linear drum-machine rhythms that occasionally give way to the serene drone of Growing's earlier years. "Highlight" is precisely what its title suggests, infectious and unsettling, like Terry Riley's "A Rainbow in Curved Air" filtered through a grinding techno lens. Yet another intriguing permutation—is a party record next?
