I was introduced to this music by one of my acting teachers in 1969. i am not sure how he knew to offer to lend me his records, but he knew. decades later, after one of those decades in japan, and the replacement of records with cds, i returned to america and visited the records section of the new york public library, and sat with headphones on and listened to this again. i don't think youtube existed yet, but it exists now, so i am happy to share this with you.
