"It Slipped My Mind" is a Robby Krieger composition from The Doors' 1972 album Full Circle, the band's final studio release before their initial disbandment. The track features a single electric guitar solo from Krieger, set against a medium-tempo rock groove in the key of E at 128 beats per minute. Without the dominant vocal presence of Jim Morrison, tracks like this one placed greater emphasis on instrumental expression, and Krieger rises to the occasion with a solo that balances melodic clarity with the edgy, slightly dissonant quality that distinguished his playing throughout The Doors' career. Krieger's guitar style, informed by his early study of flamenco and classical guitar as well as his deep love of blues, brings a unique textural quality to the recording. His solo navigates the song's harmonic landscape with the kind of relaxed confidence that comes from years of performing with Manzarek and Densmore as a tightly knit unit. Full Circle, while not achieving the commercial success of the Morrison-era albums, documents a period of creative exploration in which the remaining members sought to redefine their musical identity, with Krieger's guitar work serving as a central voice in that transformation.
