The Juma Sultan papers includes a large collection of performances from the loft era in New York City, a significant but under-documented period of jazz history. The recordings collection of circa 430 items, spanning the period from 1965-1975 (on open reel and cassette) contains unique, unreleased concert recordings, with the exception of a small amount of the collection included in the box set of Aboriginal Music Society recordings, Father of Origin (Eremite records, 2011). The recordings document not only the music of Sultan's own groups, such as the Aboriginal Music Society, but also a wide variety of recordings of other bands at Studio We, at other loft spaces in Lower Manhattan (e.g., Studio Rivbea, Artist House, the Ladies Fort, and Ali's Alley), as well as in Woodstock.
