He’s only 25, but based on his prolific output, you’d be excused for thinking Ty Segall is much older. The singer-songwriter (and guitarist and drummer) was a part-time musician until 2008, when things exploded for him musically. Since then he’s put out several solo LPs, including 2011’s Goodbye Bread, and he’s worked on albums with Epsilons, Party Fowl, the Traditional Fools, the Perverts and Tim Presley’s distortion-heavy, psychedelic-influenced White Fence. Segall (above, doing “Thank God for Sinners” on Conan) has also collaborated with Epsilons’ Mikal Cronin, and just recently their album, Reverse Shark Attack (stream it below), which came out on vinyl in 2009, received a wide release. With all of that to keep him busy, it’s surprising Segall has time to tour. But, fortunately, he seems to do it often. And as his most recent one winds down, the wunderkind comes to town for two shows. Tonight at Webster Hall is sold out, but you’re in luck because he also plays Music Hall of Williamsburg tomorrow night.
