The Roost completes its sixth annual Creative Music Series on Sunday, Sept. 14, at Spirit Abuse (1103 Fourth Street NW). The Roost and Spirit Abuse have brought some mighty, mighty programs to town this summer, hosting the legendary likes of Arnold Bodmer, Dwight Loop and Black Spirituals. The Roost ends this season in mad and meticulous style with a performance by experimentalists SHUD and bassdrumbass. SHUD, consisting of Bonnie Schmader (bass flute, flute), Katie Harlow (cello), Alicia Ultan (viola) and Rick DiZenzo (drums), relies on the jazz theoretic of American composer and coronetist Butch Morris to generate structured improvisatory soundscapes intended to create “a post-genre experience of expression.” Jeremy Bleich (electric bass), Milton Villarrubia III (drums) and Ben Wright (acoustic bass) form the trio bassdrumbass. This outfit is a heady and intuitive collaborative focused on the subtle melodic and sonic potential inherent but often overlooked in the so-called rhythm section. Entrance to this entrancement costs but five dollars, and the concert commences at 7:30pm sharp.
