LPCDreissues: Looking forward to the past

• Packaging: Gatefold sleeve

Spectrum is the groundbreaking 1973 debut solo album by drummer and composer Billy Cobham. Recorded shortly after his departure from the Mahavishnu Orchestra, it combines the rhythmic and harmonic freedom of modern jazz with the volume, energy and instrumental textures of psychedelic and progressive rock.

Cobham assembled an exceptional group of musicians for the sessions. Jan Hammer performs acoustic and electric piano and Moog synthesizer, while guitarist Tommy Bolin and bassist Lee Sklar appear on several of the album's most powerful pieces. Other contributors include Ron Carter, Joe Farrell, Ray Barretto, Jimmy Owens and John Tropea.

“Quadrant 4” opens the album at extraordinary speed, driven by Cobham's double-bass-drum technique, Hammer's electric piano and Bolin's Echoplex-treated guitar. The short electronic introduction “Searching for the Right Door” leads into the title composition, a more spacious jazz arrangement featuring horns, flute, acoustic bass and Latin percussion.

“Anxiety” acts as a tense electronic prelude to “Taurian Matador,” where rapid drumming, synthesizer and distorted guitar create one of the record's most intense performances. These contrasting pieces demonstrate Cobham's ability to move between carefully constructed ensemble writing and explosive improvisation.

The second side opens with the extended “Stratus,” built around one of the most recognisable bass patterns in jazz fusion. Its slow, heavy groove provides the foundation for gradually developing guitar, keyboard and drum passages. The rhythm was later sampled by Massive Attack for “Safe from Harm.”

Jan Hammer's brief solo-piano piece “To the Women in My Life” introduces “Le Lis,” a lighter composition featuring flute, trumpet, acoustic bass and congas. The album concludes with the electronic miniature “Snoopy's Search” and the relaxed funk groove of “Red Baron.”

Produced by Billy Cobham and engineered by Ken Scott, Spectrum became one of the most influential jazz-rock recordings of the 1970s. Its combination of exceptional musicianship, powerful studio sound and memorable compositions continues to appeal equally to jazz, progressive-rock and guitar-music listeners.

This Music On Vinyl edition presents the complete original album on heavyweight 180-gram audiophile vinyl in a gatefold sleeve.
