Brooklyn-by-way-of-Seattle jazz, roots, and chamber-influenced brass quartet the Westerlies (trumpeters Riley Mulherkar and Chloe Rowlands, and trombone players Andy Clausen and Willem de Koch) have never forgotten their Emerald City roots. They’ll return this first full weekend in February to host their second eponymous music fest, which, according to press materials, was created “to give back to the musical ecosystem that raised them by engaging local students, highlighting local talent, and facilitating explosive collaborations between artists from Seattle and beyond.” Basically, workshops at area schools by day, and concerts that find the Westerlies performing with a different guest artist by night: singer, songwriter, and multi-instrumentalist Celisse at the Royal Room on Thursday; Seattle-based pianist, composer, and singer Robin Holcomb at the Chapel Performance Space on Friday; and NYC poet duo Phil Kaye and Sarah Kay alongside local spoken word artist Troy Osaki at Town Hall Seattle on Saturday. Sunday closes with the Westerlies Fest JAM-boree of workshops, activities, a listening session, and an open rehearsal followed by a late afternoon Westerlies concert, all at Nickerson Studios. by Leilani Polk
