Six years before the release of his landmark Mother Earth’s Plantasia LP, composer and arranger Mort Garson met experimental film director Skip Sherwood, who was interested in an electronic score for his new movie, Didn’t You Hear?

While not much is known now about the exact nature of their collaboration, Here's Garson’s magnificent score as a record of those heady, early days after his life-changing discovery of the Moog synthesizer. Notable for being one of the earliest screen appearances by a young Gary Busey, Didn’t You Hear? also boasts one of the first-ever all-electronic movie scores. Though the score was first released in 1970, it sounds as adventurous and futuristic today as it must have then.
