If space rock’s essence can be distilled into a single moment, it would be Hawkwind’s 1972 tour to promote their third LP, Doremi Fasol Latido. It’s a genre that achieves an engulfing, post-psychedelic surrender reliant on few, if any, chord changes, awash in electronic “blips” and “whooshes”, and driven by motoric propulsion. If space rock has a defining album, it would be Hawkwind’s double LP from the tour, 1973’s The Space Ritual Alive in Liverpool and London. Any band that claims influence from Hawkwind is likely referring to this record; any music writer describing anything as sounding like Hawkwind is definitely referring to this album. Never mind the fact that as recently as 2019, they were still cranking out new music.
