Electronic Meditations (1970)
Everything has a beginning (with the possible exception of eternity or a circle). When it comes to Tangerine Dream’s recorded output it starts here, for the most part. With the appropriately titled "Genesis," the first song from their first album, Electronic Meditations.
Which starts out in an interesting enough fashion, as a kind of noisy soundscape using instruments of seemingly indeterminate origin. Things evolve quickly over the course of six minutes, adding more conventional instruments and building to a frenetic improvisatory workout that's akin to free jazz with a dash of psychedelia thrown in for good measure.
I’d never heard it before, so it’s an interesting curiosity. But I'm in no great hurry to listen to it again.
