SEATTLE IMPROVISED MUSIC FESTIVAL If you're looking for a less-traditional way to spend your weekend, take a pilgrimage of weird to Wallingford's Chapel Performance Space for the longest-running improvised music festival in the country. Seattle Improvised Music Festival is in its gazillionth (okay, 29th) year; this edition's lineup features four international artists as well as an impressive host of local improvisers. Oakland clarinetist/electronics tinkerer Matt Ingalls, minimalist Autoharp/electronics duo Bonnie Jones and Andrea Neumann, and guitarist/composer Joe Morris are visiting artists inspiring total fear in squares. Local artists include Gust Burns on piano/turntable/dubplate (?!), as well as freaky sax-musings from Paul Hoskin, weirdo clarinet from Beth Fleenor, several percussionists and guitarists, all sorts of clarinets and saxophones, field recordings, and who knows what else. If the weekly improv night Racer Sessions is your jam, or you just like to experience new things from time to time, it would behoove you to attend this event.
