I've got a remastered version of Space Ritual on CD.
On Monday night, heading along the M4 (largely unlit) at 11pm it was not difficult to feel like I was entering hyperspace...
Lemmy's bass on the album is really clear on this version. It is utterly unlike his music with Motorhead, and is essentially the glue that holds the entire songs together and even the dominant melodic element on many of them. Solid as a rock, massively powerful and then throwing in little runs and walking excursions with loads of improvisation.
It's easy to see why Space Ritual inspired so many people to start playing bass.
