[1] According to its announcement press release, the album is intended to be "a celebration of the diverse styles within the blues genre", and represents "the realization of [Trout's] long held dream to invite musician-friends from his 35+ year career to compose and play together with him".

[2] Alongside a core band lineup of Trout, bassist Rick Knapp and drummer Richie Hayward, Full Circle includes guest performers on every song, including former John Mayall & the Bluesbreakers bandmates John Mayall and Coco Montoya, Provogue labelmate Joe Bonamassa, and former bandleader Melvyn "Deacon" Jones.

[2] Walter Trout and the Radicals (including Knapp, drummer Joey Pafumi and keyboardist Sammy Avila) toured in promotion of Full Circle during late 2006 and early 2007.

AllMusic writer Hal Horowitz suggested that "Deep blues fans will still probably shy away due to the album's guitar heavy appeal and Trout's tendency to overextend his furious solos.

But for the blues-rocker who loves a rugged blast of electricity and barrages of notes played with no-frills intensity, this is arguably Trout's most listenable, impressive, and diverse album yet.
