The Westerlies, “an arty quartet…mixing ideas from jazz, new classical, and Appalachian folk” (The New York Times) 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.

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.

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).
