The group began when Threadgill was asked by Columbia College in Chicago, Illinois to arrange a number of Scott Joplin songs. Joplin was so strongly associated with piano that the musicians enjoyed the challenge of performing his trademark songs without piano.
Air broke up and reformed several times, and after McCall's death, Andrew Cyrille performed with the trio.
The group recorded some twelve albums, among them Air Lore from 1979, which is a recording of improvisations over more Scott Joplin songs as well as selections by Jelly Roll Morton and a Henry Threadgill original.
