Ascendant rock quartet Momma are expanding their acclaimed latest Polyvinyl album, Welcome to My Blue Sky, on Nov. 14 with four outtakes and a cover of “Christian Brothers” by the late Elliott Smith’s pre-fame band Heatmiser. A head-nodding new single, “Cross Your Heart,” is out now in tandem with a video directed by Prophet Media’s Steph Rinzler. It’s about a forbidden romance and sneaking around with another person.”Rinzler’s video finds band members Etta Friedman, Allegra Weingarten, Aron Kobayashi Ritch and Preston Fulks gallivanting around their adopted hometown of Brooklyn, N.Y. “I wanted to capture Momma in their own world, goofing around, stumbling into moments, and letting the night carry them,” she says. “What unfolds is less of a traditional music video and more of a time capsule of a night out. After their first visits to Japan and Australia early next year, the band will help anchor the Something in the Way festival alongside Sunny Day Real Estate, Explosions in the Sky and the Hotelier from Jan. 31-Feb. 1 in Boston.
