Any sci-fi fan with long memories probably remembers those 1970s' DAW paperback editions of Michael Moorcock's sword-and-sorcery novels, with their images of heavily armored, very muscular warriors, carrying large swords and standing against eerie land- and starscapes. Take that imagery, throw in some terminology and names seemingly lifted from the Marvel Comics of the era (The Watcher, etc.) and particle physics articles of the period, translate it into loud but articulate hard rock music, and that's more or less what Hawkwind is about. One of England's longest-enduring heavy metal bands, Hawkwind was formed during the late '60s, just as art-rock was coming into its own. They combined bold guitar, synthesizer, and Mellotron sounds, creating heavy metal music that seemed to cross paths with Chuck Berry and the Moody Blues without sounding like either of them. At their best, their early records sounded like the Beatles of "Yer Blues" combined with the Cream of "I Feel Free." The introduction of lyrics steeped in science fiction and drug effects on their second album helped define the group and separate them from the competition -- in some ways they were like Pink Floyd with more of a rock & roll beat and a vengeance. They've never charted a record anywhere near the same heights, but it's a sign of the dedication of the fans they do have that the group has dozens of albums available, including archival releases of decades-old live shows and multiple compilations.
