At Roulette, The Westerlies join guitarist Bill Frisell for an album-release set that places his open-ended song forms beside the quartet’s two-trumpet, two-trombone sound. Frisell’s writing moves easily between jazz, folk, country, and rock, while The Westerlies draw on contemporary classical and improvised traditions, often using extended techniques and restrained textures. In a city where genre borders rarely hold, this collaboration reads as a small history of American vernacular music told through brass and guitar. The result suggests intimacy at chamber scale without losing improvisational risk.
