Spectrum Road is the debut album by the American supergroup of the same name, featuring bassist and vocalist Jack Bruce, guitarist Vernon Reid, keyboard player John Medeski, and drummer Cindy Blackman Santana.

"[7] In a review for AllMusic, Thom Jurek wrote: "Spectrum Road's self-titled debut delivers in full on the supergroup promise; in addition, they provide the kind of forward-looking tribute that a pioneer like Williams truly deserves.

The ferocious (yet nuanced) recorded performance throws down a gauntlet, as well, and clears the decks of any expectations listeners might bring to the experience... For anyone with a soft spot for the icons of prog-rock and jazz-fusion...

"[8] Doug Collette of All About Jazz wrote: "Pure power takes precedence over finesse on Spectrum Road, but just barely... there's enough loyalty to the source... without undermining the spontaneity of the moment(s).

"[9] In an article for Burning Ambulance, Phil Freeman stated that the musicians "absorb tunes from all versions of Lifetime into a single encompassing vision that's loud, hard-rocking, sometimes funky, frequently quite exploratory, and more adventurous than most repertory projects or tribute bands.

"[12] Writing for Something Else!, S. Victor Aaron commented: "Spectrum Road reintroduces the limitless possibilities that were abundant... when Williams and his fearless Lifetime band were racing across the frontier and leaving most everyone behind.
