snobb "Levels And Degrees Of Light",released more than a half-century ago, is an almost forgotten cornerstone evidence of the entire epoch, and that's a shame. One of AACM founder pianist Muhal Richard Abrams (or simply Richard Abrams at the time of release) debut contains lot of ideas which have been developed for upcoming decades with a great success.

Just three longish compositions, all different but beautiful in their own way. One big surprise is lot of ambient sounds, similar to "white noise" on two longest album's compositions, recalling early synthesizers sound. Not common in jazz, early (rare and really expensive) synthesizers attracted interest of some known pianists, as Paul Bley or Richard Teitelbaum among others,so there are some recordings coming from 70s with use of this instrument,but the biggest surprise is that there on "Levels And Degrees Of Light" no electronic devices are used at all!

Main sources of ambient noise are Gordon Emmanuel vibes on opener and Leroy Jenkins violin on "The Bird Song". On "Levels And Degrees Of Light" classically trained vocalist Penelope Taylor sings over the ambient sounds, with addition of Abrams soloing on clarinet. Album's longest composition "The Bird Song" (filling all B-side on original vinyl release, but stated second in line on CD reissue)contains characteristic for 60s recitative poetry (read by David Moore).

"My Thoughts Are My Future - Now And Forever" which closes digital edition of this album, is shorter and more usual for the time groovy high-energy free jazz composition with staccato piano,sax soloing from Anthony Braxton (most probably his first ever recorded work) and lot of space for drummer Thurman Barker.

The album which probably doesn't sound such a radical from time distance at the day of release was innovative and perfectly illustrated the musical concept of then newly established musical school/movement of innovative Chicagoan artists which is still alive and active nowadays.
