An indie singer/songwriter with a reflective, literate style in the vein of influences like Paul Simon and Joni Mitchell, Ethan Gruska was half of the indie pop duo the Belle Brigade before launching a solo career with 2017's Slowmotionary. He also branched out as a producer and songwriter, working on Phoebe Bridgers' debut album, Stranger in the Alps, and co-penning songs with John Legend and Kimbra, among others. In 2020, he released his sophomore album, En Garde, which again found him working with Bridgers. He also collaborated with Bon Iver on the 2022 single "So Unimportant."
