Ah, Hawkwind.
"In Search of Space" and especially "Doremi Fasol Latido" have to be seen in the context of the developing vision and plans for the "Space Ritual" tour and subsequent double LP. One of the best live LPs of the period I think. Not for pristine recording quality but for capturing the moment.
Having said that, I was 13 in 73/4 when "The Space Ritual" was toured and I first saw Hawkwind in 1979. It's a huge pity Space Ritual wasn't filmed :-( . Seen them rather a lot since then, including the only performance of the Space Ritual by Hawkwind since 1974, done as a one off, never again gig for animal charities in 2014 and this time videoed as well as recorded. Not just a recreation of the original either, but
The current line-up is seriously good live and releases some good recordings as well, new stuff and rearrangements and retakes on the older material, and is yet another of the many shades of Hawkwind there's been over the last 45 or so years (and well over 60 long or short term members, but always with Dave Brock at the helm). They still record, tour and run some very nice mini-festivals with interesting line-ups and no concept of "backstage" if you know what I mean. Good people.
If you've not head it, "Quark, Strangeness and Charm" is worth a listen, quite a gear change from the heavier stuff that preceded it.
Some bands find a style that works for them and then stick with it for their entire careers, some are more willing to experiment and develop over time. Both approaches can work (or fail). Personally I feel a little sorry for those who had two or three hit singles in the 50s and early 60s then by the late 80s found themselves on revival/nostalgia tours with other similar bands, each doomed forever to repeat its 15 or 20 minutes of fame. That strikes me as the opposite of a fun way to make a living.
To get back to somewhere near the topic, on the subject of bands booked by Hawkwind, Prime Sinister, a French (metal)ish band are worth having a listen to if you've not come across them. I think they were resident in LA for a while, so they may be better known in the US than UK.
