Much like his frequent collaborator, Ty Segall, Mikal Cronin is a walking, talking, rocking youtube of music history. Together, they’ve thrashed through garage, punk, and proto-metal in the Ty Segall band, on solo releases, on tour, and under the banner Ty Segall and Mikal Cronin for an album, too. And again, like Segall, Cronin is no stranger to the modest pop song. Segall showed off his own pop fancy on Goodbye Bread, a 2011 album light on gnarly, but heavy on the Beatles, Beach Boys, and Big Star. Now, it’s Cronin’s turn to let his own pop-smarts shine with “Weight,” the second preview track from his Merge Records debut out on May 7th, and lord, does Cronin shine — as a vocalist, a songwriter, multi-instrumentalist, and his own man.
