Woodstock’s seminal Creative Music Studio (CMS), founded by the husband and wife team of pianist/vibraphonist Karl Berger and Ingrid Sertso, was not only a trailblazer for musicians’ assimilation of global sounds into jazz but home to one of the earliest collective educational initiatives in jazz. In 2013 Berger restored and digitalized around 400 hours’ worth of tapes recorded in workshop or live concert situations at the CMS between 1973 and 1984. This is the second 3CD set release in the series. Subdivided into ‘Small Ensembles’, ‘Large Ensembles’; and ‘ World Music’ gives a sense of the open-minded diversity and breadth of the Studio’s approach. Berger describes these albums as documenting, “a cross-section of the cross-pollination that occurred regularly at CMS”. This hugely intriguing artefact bears that out entirely. No better example of that is on the ‘m’ CD with AACM saxophonist Maurice Macintyre’s Kalaparusha trio’s blend of spiritual jazz and deep Chicago groove sits alongside a Lee Konitz led full-on bebop version of Sonny Rollins’ ‘Oleo’. It’s other eye-opening discoveries include a duo between Anthony Braxton and Marilyn Crispell in 1977 at a time when the pianist had enrolled both as teaching staff and student, only later joining Braxton in his ‘classic’ quartet, as did Gerry Hemingway who leads his own band here too. That’s one of three superb tracks on the ‘large ensemble’ CD that also contains a 27-minute spiritual jazz epic which never outstays its welcome by the Don Cherry orchestra featuring Nana Vasconcelos. The third is a real gem by trumpeter Baikida Carroll’s raw, spaced-out orchestra; listen closely and you can hear an antecedent to nu-cosmic jazz star Kamasi Washington. The ‘World Music’ CD sounds these days more jazz than world. Paulo Moura’s sizzling Brazilian jazz, the pioneering Turkish jazz legend Ismet Siral (a central figure at CMS) and Oregon’s Collin Walcott performing in 1981 are among its many awe-inspiring moments.
