Our burg's elder statesman of free improvisation, Wally Shoup (Sat May 17, 8 pm, $8), is finally garnering some well-deserved recognition. To celebrate a pair of new discs on Leo Records, alto saxophonist Shoup has enlisted Reuben Radding and drummer Bob Rees. Both releases, Fusillades & Lamentations and Live at Tonic, bristle with bold, uncompromising improvisation. An old-school, paint-peeling session, Live at Tonic may attract more attention due to the presence of Sonic Youth guitarist Thurston Moore, but Fusillades & Lamentations feels more like Shoup: Delicate textures tussle with skittering, soul-wrenching passages.
While most of Polestar's festival focuses on free improvisation, new composition gets a nod with the double bill of Mikro Propaganda and Sorelle (Sun May 18, 8 pm, $8). Mikro Propaganda, the duo of fretless guitarist Tom Baker and percussionist Dale Speicher, play solos and duos by Xenakis, Ligeti, and Christian Wolff. They'll also premiere a new work by ex-Seattleite Christian Asplund. The chamber music quartet Sorelle perform works by Takemitsu, Crumb, Ravel, and Sorelle's flutist, Sarah Bassingthwaighte.
