Mary Caroline Richards spent time at Black Mountain College, formed and lived on a Long Island commume from 1954-1964, wrote poems about pottery and published a book about centering in the 1960s that received a lot of attention, was a long-time friend of John Cage. When Cage did an academic year at Wesleyan University in 1960-61, he used his leverage there to arrange a poetry reading for Richards. PennSound has only one recording of M.C. Richards — made at Indre Studios in Philadelphia on May 5, 1997.
One of the poems she performed on that occasion was "For John Cage on His 75th Birthday": MP3.
