Notes

A compilation of both Eric Dolphy LPs recorded for Douglas along with the best alternate takes, all recorded in mono, adding 85 minutes of previously unissued music. The original LPs Conversations and Iron Man were issued in stereo, but those master tapes have been lost. These tapes were left by Eric Dolphy with composer Hale Smith and his wife Juanita prior to his ill-fated tour of Europe in 1964. They were in the possession of flautist James Newton when they were discovered.All tracks recorded July 1 & 3, 1963 in New York City, except 2-6, which was recorded in Ann Arbor, MIchigan on March 2, 1964.Made in USA
