From 1962-1968, he composed 22 Light Poems [2] without a computer. The poems are all combinatorial and loosely composed upon algorithmic method, sometimes he inserts his own phrases, sometimes he uses phrases from obscure sources (the back of a collage) as glue between algorithmically generated material. For 22 Light Poems Mac Low assembled 280 names of different kinds of light, sorted them into rows and columns and associated each column with a letter from his name or his wife’s name and a playing card. Then he shuffled the playing cards and whenever he needed or felt impelled to insert a light word selected a card.
