"Hawkwind's fifth studio album found the band enjoying a rare oasis of stability after the multitudinous personnel shifts of the past five years. Only the recruitment of a second drummer, Alan Powell, disturbed the equanimity of the lineup that created the previous year's Hall of the Mountain Grill, although it would soon be time to change again. By the end of the year, bassist Lemmy had departed, vocalist Robert Calvert had rejoined, and the group's career-long relationship with United Artists would be over. In the meantime, Warrior on the Edge of Time ensured that it was brainstorming business as usual, featuring crisp, Can and Neu!-style motorik-grooved drumming on the pounding 'Opa-Loka' and gleaming synths on the supremely-psychedelic 'The Golden Void'.
Decorated with a magnificent sleeve that unfolded into the shape of a shield, Warrior on the Edge of Time delivered some of Hawkwind's best-loved future showstoppers -- Simon House's far-reaching Spiral Galaxy 28948, the frenetic Assault and Battery, and the monstrous Magnu all made their bow here, while the accompanying Kings of Speed single was certainly a big hit in the youth clubs of the day, even if it did steadfastly avoid the chart. Remarkable, too, is The Golden Void, a stately bolero set, indeed, on the edge of time and buffeted by one of the band's most impressive ever instrumental performances." - All Music
