One of a number of sessions cut at the Choreographers' Workshop, this 1963 set establishes Sun Ra's Arkestra as a

New York band, sonically coupled to developments in the decidedly urbane downtown arts underground.

The stargazing clamor of the music reflects the intensity of a cultural crossroads where concrete and dust

pervade any skyward view, from East 3rd Street to Mars and beyond. One of Sun Ra's rarest releases, it had negligible circulation through shops.
