The fourth in the An Ayler Xmas series from saxophonist Mars Williams, expands to a double CD with recordings from two bands: Josh Berman, Jim Baker, Kent Kessler, Brian Sandstrom & Steve Hunt (Chicago); and Steve Swell, Hilliard Greene, Chris Corsano, Nels Cline & Fred Lonberg-Holm (NYC); in incredible free jazz mashups and bash-ups of Holiday favorites.

After a tour through upstate New York State with Chicago cellist and electronic artist Fred Lonberg-Holm, saxophonist Frode Gjerstad headed to New York City for a planned trio recording which evolved into this informed quartet with Steve Swell on trombone and William Parker on bass, tuba, cornet & flutes, an outstanding example of Transatlanic collective improvisation.

An essential asset of the NY Downtown scene since the 70s, trombonist Steve Swell leads and composes for an exemplary and uniquely orchestrated sextet bridging generations: Jason Kao Hwang on violin, viola & electronics, Ariel Bart on harmonica, Fred Lonberg-Holm on cello & electronics, Robert Boston on piano & organ, and Andrew Cyrille on drums & percussion.

Not Two Records celebrates their 20th Anniversary with a festival in Wlen, Poland, inviting 13 of the finest European & US improvisers--Guy, Leandre, Mazur, Nilssen-Love, Kaucic, Fernandez, Gustafsson, Vandermark, Trzaska, Brotzmann, Swell, Holmlander, & Homburg--performing in configurations from duo to quintet, released in a limited 5-CD wooden box set.

Focusing on melody, rhythm, harmony, and texture, violinist/composer Jason Kao Hwang's Sing House employs a perceptive and swinging blend of Western and Eastern influences as his impressive band with Andrew Drury on drums, Ken Filiano on bass, Chris Forbes on piano, and Steve Swell on trombone present four lyrical, propulsive and wonderfully embraceable "songs".

Composer & violinist Jason Kao Hwang wrote "Blood" as he meditated upon the traumas of war retained within the body as unspoken vibrations that reverberate across community and generations, performed in an incredible east/west octet with Taylor Ho Bynum (cornet), Joseph Daley (tuba), Andrew Drury (drums), Ken Filiano (bass), Sun Li (pipa), Steve Swell (trombone), & Wang Guowei (erh).

Saxophonist Sabir Mateen's NY based Shapes, Textures, and Sound Ensemble with Steve Swell on trombone, Matt Lavelle on trumpet, Matthew Heyner on bass and Michael T.A. Thompson on drums, run though a gamut of post-bop and collective, creative jazz forms with energy, incredible dexterity, and tremendous group interplay, a great example of the modern spirit of jazz.

The trio of Guillermo Gregorio (clarinet), Steve Swell (trombone) and Pandelis Karayorgis (piano) use their unique selection of instruments to play an original set of composition and improv.

Tsahar's 60-minute suite with his NY heavyweights Zoanthropic Orchestra is a sort of self-portrait in sound, drawing on auditory memories from his childhood on.
