The Acorn is a Canadian indie folk band from Ottawa, Ontario, formed in 2003. Rolf Klausener is their principal songwriter, as well as vocalist and guitarist. Their most recent album, "No Ghost", came out in summer 2010. Anchored by vivid songwriting and eclectic instrumentation, The Acorn produce an original brand of experimental, popular folk music that effortlessly marries modern and traditional forms. Inspired by the natural beauty of the Outaouais region, and with his principle projects all on hiatus, Rolf Klausener started writing under the moniker The Acorn in the summer of 2002.
