Henry Threadgill is an American composer, saxophonist and flautist. One of the most important composers and arrangers in avant-garde jazz, Threadgill came to prominence in the 1970s leading ensembles with unusual instrumentation and often incorporating a range of non-jazz genres. Threadgill, aside from being a remarkable alto saxophone player, is one of the most imaginative of jazz composers today. This set includes seven albums Live Air, Air Mail, Live at Montreal, Air Show No.1, Spirit of Nuff...Nuff, Song Out of My Trees and Flutistry.
