Recorded live with Sonny Murray and Gary Peacock in 1964 — just a month before the Spiritual Unity session — already veering so intensely and steeply way outwards from core, morphemic scraps of tunes like Ghosts and Spirits.

His first recordings, pre-Trane. Two previously unreleased sessions with Don Cherry and Paul Bley; his debut as a leader; and the first issue ever of the complete end-of-1964 concerts with Sun Ra at Judson Hall (Sanders’ only known recordings with the Arkestra).

The Alabama-born saxophonist and clarinettist in 1966, with Sonny Sharrock, Byard Lancaster, Clifford Thornton, Karl Berger, Henry Grimes and co.

An anti-war collage of words and sounds from August 6, 1966, including contributions from a plastic clock-radio, The Velvet Underground, Gerard Malanga, Marion Brown, Allen Ginsberg, Ishmael Reed, Andy Warhol (standing around silently) and Ed Sanders.

All three volumes, with each disc enhanced, containing archival photos, critical writings and historical videos, including the eighteen-minute documentary Sun Ra Spaceways.

From 1966, burning, mostly free-form, a quintet featuring the missus Barbara Donald’s brilliant trumpet-playing, and an up-and-coming John Hicks.

With different lineups in 1966, including pianists Ran Blake, Burton Greene and Dave Burrell; and Giuseppi Logan.

Primitive rhythms and offbeat pop by this one-man-band (laptop, guitar, vocals), going since the 1970s, and championed by Animal Collective and Half Japanese.
