The Chicago trio Air was at a high point on this 1980 date, thanks in part to remarkable percussive foundations provided by the late Steve McCall
and his interaction with bassist Fred Hopkins
, plus the amazing solos and versatility of nominal leader Henry Threadgill
. Besides alto and tenor sax, flute, and bass flute, Threadgill
plays his own unique instrument called the hubkaphone and makes it just as memorable a weapon as the other horns.
