One person who, after hearing the album, experienced an epiphany that significantly altered the course of his career was Jeff Beck. “Spectrum changed my whole musical outlook,” he once explained. “(It) gave me new life at the time, on top of the Mahavishnu records. It represented a whole area that was as exciting to me as when I first heard ‘Hound Dog’ by Elvis Presley. They were so inspirational to me that I started to adopt that type of music. Tommy’s guitar playing on Spectrum is fantastic, while Jan can flatten you with the first few notes.” The album provided the impetus for Beck’s landmark Blow by Blow, Wired, and the formation of a long and fruitful musical alliance with Hammer, which turned out to be a marriage made in heaven.
