Here is the world streaming premiere of “Avrils,” from alto saxophonist Michael Attias’ upcoming new album ‘Quartet Music Vol. II: Kardamon Fall.’

Spin-offs usually aren’t as successful as the original thing. That axiom never applies to Ivo Perelman projects, though, and for ‘Duologues 1-Turning Point,’ a peak performing Perelman gets Tom Rainey’s best.

Collaborating with Mark Helias and Tom Rainey makes ‘Truth Seeker’ a whole new, tantalizing artistic quest for Ivo Perelman.

By playing different songs after several more years of further developing their chemistry, Science Friction’s ‘No Tamales on Wednesday’ qualifies as a welcome official ‘new’ album by this long-defunct Tim Berne group.

Satoko Fujii’s genius can be difficult to encapsulate on a single record. We may finally have a good starting point with ‘Hyaku: One Hundred Dreams.’

Whether under a freeway or in the studio, Tony Malaby can make good art out of his surroundings and does so again with ‘The Cave of Winds.’

‘The Art Spirit’ does a pretty good job showing what Ben Goldberg, Nels Cline and Tom Rainey are capable of individually and a great job showing what they can do collectively with no premeditation.

‘Sensitive’ documents the gig where Tim Berne’s Hardcell unit got started, as well as Berne’s fruitful association with keyboardist Craig Taborn.

Ben Monder, Tony Malaby and Tom Rainey are superb jazz musicians but for the live improv set ‘Live At The 55 Bar,’ they were clearly reaching for something beyond the bounds of jazz or any other genre.

There were two discoveries with ‘Science Friction +size’: When a quartet discovered new possibilities with a trumpeter, and when Tim Berne scraped a shiny disc off the floor.
