The Westerlies

The Westerlies "Fight On" is GRAMMY-nominated! (Best Arrangement, Instrumental or A Cappella) John’s University, and the University of Washington.

The Westerlies, “an arty quartet…mixing ideas from jazz, new classical, and Appalachian folk” (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. Equally at home in concert halls and living rooms, 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). The Westerlies’ upcoming engagements include performances at Bay Chamber Concerts, Southern Exposure New Music Series (University of South Carolina), and Michigan State University, and among others. Recent performances include New Music at the Nasher, Noe Valley Chamber Music, Earshot Jazz Festival, the Norton Center for the Arts, the Moore Theatre, Shenandoah University, Purdue Convocations, the Oxford Performing Arts Center, Luther College, the Schubert Club, St. The ensemble was also featured with Fleet Foxes at Coachella, the Hollywood Bowl, the Greek Theatre Berkeley, Red Rocks, the Newport Folk Festival, Merriweather Post Pavilion, the Santa Fe Opera, Outside Lands in San Francisco, Panorama New York City, and the Pitchfork Music Festival. The ensemble has produced numerous critically acclaimed albums of genre-defying music. In May 2021, The Westerlies released Bricolage (Westerlies Records), a collaborative album of improvisations with pianist/composer Conrad Tao. 2021 also saw the release of This Land, the ensemble’s collaboration with GRAMMY-nominated vocalist Theo Bleckmann. The Westerlies have produced three albums of quartet music: their 2014 debut, Wish the Children Would Come On Home: The Music of Wayne Horvitz (Songlines), a 2016 double-CD of primarily original compositions, The Westerlies (Songlines), and their 2020 release, Wherein Lies the Good (Westerlies Records). 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). Education and community engagement are core elements of The Westerlies' mission. Starting in Fall 2021, The Westerlies will be the first small ensemble-in-residence at the School of Jazz and Contemporary Music at The New School. The Westerlies produce an annual music festival in Seattle called Westerlies Fest, which combines evening performances featuring numerous guest artists, an all-day open-to-the-public creative music jamboree, and workshops in local public schools. The festival’s educational programming reaches over 1,000 students in Seattle and surrounding underserved areas every year. The Westerlies have engaged students of all ages and abilities around the country with their innovative assemblies and masterclasses, promoting the values of cooperation and inclusion through music. They have completed educational residencies with Clefworks (Montgomery, AL), Orcas Island Chamber Music Festival (Orcas Island, WA), the School District of Osceola County (Osceola County, Florida), and Highline Public Schools (Burien, WA), among others. They have also taught masterclasses at The Juilliard School, Manhattan School of Music, Yale School of Music, The Colburn School, and a variety of other colleges and universities. As a 501(c)(3) organization, The Westerlies are on a mission to amplify unheard voices, paint new sonic landscapes, and cultivate a global community. The Westerlies are committed to dismantling racism, sexism, and economic inequality in their field, and aim to reflect their values of diversity and inclusion in the music they make and the spaces they occupy.

Today marks five years of “Songbook, Vol. 1.”
These seven songs, recorded in Andy’s living room in the spring of 2021, documented us coming back together after a year apart during the pandemic. The EP also kicked off our “Songbook” EP series, which has led to Vol. 2, featuring original compositions, and Vol. 3, featuring songs by our friends and collaborators. Just wait until you hear Vol. 4…

"The local-global connection was most apparent on Saturday, when Mexican folk singer Silvana Estrada hit the Mural Amphitheatre with her former tourmates, The Westerlies, sitting in. The Seattle brass quartet and a cellist helped Estrada elevate her gorgeous acoustic songs into lush, ornate chamber folk movements that had hippies dancing, rockers grinning and Chicano hearts singing."

Thanks for the shoutout, The Seattle Times! What a joy to get to join Silvana Estrada and her band over the weekend at Bumbershoot.

With an intentional, finely tuned lineup, organizers offered the clearest vision of what Bumbershoot can — and should — be.

Reunion with Silvana Estrada and it feels so good! Playing Bumbershoot today for the hometown crowd ☂️

"During the 2020-2021 pandemic era, the guitarist-composer jotted down musical sketches in a notebook, which he then gifted to the band to freely develop, arrange and put their spin on.
Frisell’s unmistakable style and ethos translate well to the
brass quartet’s Have You Heard? The Music of Bill Frisell,
Vol. 1."

Thanks to The New York City Jazz Record for including a review of our latest record in their August issue! Stay tuned for Volume 2...
