Two performances of Chicago reedist and composer Guillermo Gregorio's graphic score "Moholy 2", inspired by the artwork of László Moholy-Nagy, recorded in two conductions at the Experimental Sound Studio in Chicago in 2007 & 2008 by the trio of Gregorio on clarinets & alto sax, Damon Smith on double bass, and Jerome Bryerton on percussion, cymbals and drums.

Four settings with improvising bass guitarist Rafal Mazur, 4 CDs, the first a solo studio recording of two extended improvisations; the 2nd a duo with clarinetist Guillermo Gregorio; the 3rd a live concert at Baza Club in Krakow with trumpeter Artur Majewski; the 4th a quintet session with Gregorio, Satoko Fujii (piano), Natsuki Tamura (trumpet), Ramon Lopez (drums).

A collection of compositions from clarinetist Guillermo Gregorio alongside collective improvisations from the trio with bassist Joe Fonda and drummer Ramon Lopez, sophisticated chamber-oriented jazz from masterful players recording in the studio in New Jersey, as they explore the musical intersection of disparate cultural, geographic and life experiences.

Known best for his Chicago trios, Argentinian born clarinetist Guillermo Gregorio joins forces with New York contrabassist Brandon Lopez for 12 "episodes" of free improvisation that never loses track of a jazz basis, both players using an arsenal of techniques, from circular breathing to extracting sound from the physical forms of their instruments.

Guillermo Gregorio produces a series of compositions that reinterprets the structural concepts of Constructivism, Concretism, and Madi, focusing on the physicality of sound.

In 2000, saxophonist Mats Gustafsson and curator John Corbett organized a 16-piece free music big-band featuring key members of the Chicago and Swedish scenes, recording these two impressive, ecstatic, and explosive works.

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.
