Spectrum is the debut album of Billy Cobham. Released in 1973, Spectrum is regarded as one of the most important and essential albums within the fields of drummers and the jazz fusion genre. The album contains much influence of the music of Miles Davis and Mahavishnu Orchestra, with whom Cobham had previously collaborated extensively. Generally, Spectrum is considered to be Cobham's best album up to this day, and does embody a role as important as the work by Miles Davis, Weather Report, or Mahavishnu Orchestra among the development of the jazz fusion genre.
Tommy Bolin, who would go on to join the hard rock band Deep Purple two years later, plays the lead guitar.
