It never fails to seem odd to me how many of the classic free jazz records of the earlier waves were released on major labels.
A lot of free / avant garde jazz records from the 1960s, particularly Archie Shepp's Impulse!s and Braxton's Aristas, are even sequenced like pop records, with what appears to be the catchy "big single" as the first track, and then a B side with lesser or more difficult material.
Was this just an attractive way to sequence an album, or does this reflect actual singles releases? If so, were any of them "hits"? Even if not released as a single, did they get played on the radio or TV? What kind of stations or programmes touched that stuff?
The era of free jazz on major labels goes on for am incredibly long time: all the way to the late 1970s / over a decade. Were these labels making money on these things?
