This is a digitally remastered (1996) offering with considerable improvement on the sound quality of the vinyl copy (my 2nd - the first wore out) that I own. Lemmy's bass lines drive the whole performance along and you can hear them crisp and clean on this CD. This is a monster album to shake the walls.Play it loud in the car so that the bass makes doors and floor reverberate and the rest of the Hawkwind sonic assault washes over you.I agree that Space Ritual is 'a brutal sensory onslaught'and is best listened to in its entirety when in the right mood.It is not everyone's cup of tea.It is difficult to pick out highlights from this one but if I cannot listen to all of it in one go I tend to go for Master of The Universe , Brainstorm and Space is Deep.
