Well, this is a bittersweet surprise. On the heels of Kim Deal’s announcement that she was leaving the Pixies comes this new track–the band’s first since 2004–which sounds to be one of Deal’s final moments as a member. “Bagboy” starts off uninspiring, with Frank Black doing a wordier version of his neurotic talk-singing over sparse guitar and drums, and you’re wondering whether Kim’s there or not. And then the chorus hits, and she’s there, and it’s ecstatic. Listen (and watch the Lamar + Nik-directed video) above.
