eau claire is an absolute hotbed for live music; if you need any convincing, just consult an events calendar. aside from touring bands and established local acts that frequent bars and basements, the scene regularly plays host to exciting one-off collaborations that rarely venture into a recording studio. one such exception is ’58 belvedere, an experimental jazz trio featuring three familiar faces: pat kuehn, who lends his upright bass skills to rivers, dave power, the mustachioed drummer for adelyn rose who moonlights under the electronic moniker of white dune, and dean granros, an enigmatic mainstay of eau claire’s live jazz circuit. the outfit is gearing up to release their debut, rustic libertines, in early january, and we’re excited to share its lead single. “i don’t know” is a seven-minute propulsion of the endless ideas that spew forth from granros’ guitar fretboard, which are accompanied by an insistent bass ostinato and crisp drumming. the trio’s interplay on the song’s back half is particularly engaging and serves as a warm introduction for what the rest of rustic libertines will inevitably bring. dig in below.
