“Genre bending” has long been just another genre to the music business, but it’s nevertheless what we purvey in this show which honors the 50th anniversary of The Residents’ Not Available album with a look at their brand of minimal, lo-fi, Partchian rock-n-roll, whose remnants are discernable in recent tracks by Yikii, Błoto and Joe Santa Maria. We also hear the superhuman soprano Barbara Hannigan tackle John Zorn’s sprawling Kalevala-inspired song cycle Jumalattaret in its premiere recording, while Bryce Dessner offers a different kind of goddess-oriented crossover on his new album Solos, and Ryuichi Sakamoto crosses his own thresholds in his posthumously-released album Opus. Tom Varner, Jessica Ackerley and Patricia Brennan offer fresh takes on free improvisation, while Matt Shipp’s latest solo album blends Cecil Taylor, McCoy Tyner and Charles Ives, leading us to a Concord Sonata cameo via Donald Berman’s new traversal of that most monumental of all modern piano compositions.
