“When not pressing the valves on his trumpet or the record button on his tape recorder, [Louis] Armstrong’s fingers found other arts with which to occupy themselves. One of them was collage, which became a visual outlet for his improvisational genius. The story goes that he did a series of collages on paper and tacked them up on the wall of his den, but [his wife] Lucille, who had supervised the purchase and interior decoration of their house in Corona, Queens, objected. Armstrong decided to use his extensive library of tapes as a canvas instead, and the result is a collection of some five hundred decorated reel-to-reel boxes, one thousand collages counting front and back.
