Two years deep into the 20th anniversary tour for his band’s – or rather, loose-knit collective’s – most beloved album, Kevin Drew is releasing his third solo album. It’s called Aging. You cannot accuse Kevin Drew of lacking a sense of humor. And you likewise cannot accuse You Forgot It in People of aging. More than any of their Aughts indie contemporaries, the smeary, crayon-colored post-pop abstractions of Broken Social Scene’s sophomore breakthrough seem permanently unstuck in time. Indeed, nearly every song has become a mixtape perennial for successive generations of lovestruck teenagers (remember when Lorde name-dropped “Lover’s Spit” on “Ribs”?).
