How the hell do four of Burlington’s busiest and most prolific musicians find time to form a new band? They’re rock stars, duh. Known as the Welterweights, this rock-and-roll quartet features singer-songwriters Kelly Ravin, Lowell Thompson and Erin Cassels-Brown, as well as Future Fields producer and Madaila guitarist Willoughby Morse. The band operates as a co-op and collectively interprets each of its three songwriters’ material with a burly, lovelorn sound. For a sneak peek, check out the band’s performance on Vermont Public Radio’s in-studio music series, “Live From the Fort.” Catch the Welterweights on Saturday, March 25, at the Higher Ground Showcase Lounge in South Burlington. Locals Ellen Degenerates open.
