Dr. Eugene Chadbourne

Spy Music Festival. Eugene Chadbourne, a veteran guitarist-banjoist whose work mashes together free improvisation and skewed roots music, drops by Vaudeville Park for a collaboration—to be continued in the studio on July 4—with avant-jazzy Merle Haggard tribute band Bryan and the Haggards. Chadbourne will also perform with Pull My Daisy, a multimedia duo including banjo-toting local art-popster Baby Copperhead.
