Having Never Written a Note for Percussion (1971)

Four years later, Tenney gave us his best known composition, written on the back of a postcard.

Ten years after that, his "Septet" (1981) for six electric guitars and bass.

(Oh, and tonight at Selectors' Records, Luke Fowler, Sarah Davachi and Joshua Stevenson pay tribute to Martin Bartlett in their performance entitled "Music from the Black Box".)
