I came across this ticket stub for a “Double-Up” concert produced by Koncepts Cultural Gallery on October 16, 1993 at the James Moore Theater in the Oakland Museum. The concert featured two duos, Roscoe Mitchell & Malachi Favors Maghostut; and Horace Tapscott & Roberto Miranda.

I can still hear Roscoe playing the soprano sax (or was it sopranino) without pause using circular breathing.

I’m posting this in the hope that photos or a recording of the event exists.
