The Westerlies are a New York-based brass quartet comprised of childhood friends from Seattle: Riley Mulherkar and Chloe Rowlands on trumpet, and Andy Clausen and Willem de Koch on trombone.

Formed in 2011, the self-described “accidental brass quartet” takes its name from the prevailing winds that travel from the West to the East. “Skilled interpreters who are also adept improvisers” (NPR’s Fresh Air), The Westerlies explore jazz, roots, and chamber music influences to create the rarest of hybrids: music that is both "folk-like and composerly, lovely and intellectually rigorous” (NPR Music). From Carnegie Hall to Coachella, The Westerlies navigate a wide array of venues and projects with the precision of a string quartet, the audacity of a rock band, and the charm of a family sing-along.

The ensemble has produced two critically acclaimed albums of genre-defying chamber music: their 2014 debut, Wish the Children Would Come On Home: The Music of Wayne Horvitz (Songlines), and a 2016 double-CD of primarily original compositions, The Westerlies (Songlines). Sought-after collaborators, The Westerlies are also featured on recordings by Fleet Foxes (Nonesuch), Vieux Farka Touré (Six Degrees Records), Common (Lakeshore) and Dave Douglas (Greenleaf). The Westerlies will release their third full-length album, "Wherein Lies the Good" in early 2020.
