As many live jazz videos that have been uploaded to You Tube, coming across one of Air or even (New) Air (heck there aren't even one of Henry Threadgill's great 80s Sextet(t)), have proven a fruitless. That is, until yesterday.
While the video was uploaded a year or so ago, it was buried several pages into a search for "Threadgill" that I conducted last night. The video is taken from a film called A Place For Jazz, filmed live at the 1369 Jazz Club in Somerville, Ma., as part of a documentary on that venue, which closed in 1988. There is more info on the club and the documentary here:
Andrew Cyrille joins Henry Threadgill and Fred Hopkins here, which suggests this was filmed sometime around 1986, when Cyrille also joined Hopkins and Threadgill for gigs in Europe under the name (New) Air (Pheeroan AkLaff had taken over the drum stool after Steve McCall left in 1982).
It's a short clip, and not one of the band at their most ferocious or, *ahem* killing, but a gem nonetheless.
