"Good Rockin'" is The Doors' rendition of Roy Brown's classic rhythm and blues song, recorded for the 1972 album Full Circle. This cover represents the post-Jim Morrison Doors' engagement with the roots music that had always underpinned rock and roll. The track features solos from both guitarist Robby Krieger and keyboardist Ray Manzarek, each taking a single chorus over the 12-bar blues form in the key of A. Krieger's electric guitar solo, taken at a moderate tempo of 144 beats per minute, reflects his characteristic blend of rock intensity and melodic inventiveness, while Manzarek's piano solo channels the boogie-woogie and barrelhouse traditions that informed his keyboard style throughout his career. The choice to cover this particular song is notable, as Roy Brown's original 1947 recording is widely considered one of the foundational texts of rock and roll, later made even more famous by Wynton Harris's version. By revisiting this material as a trio, the surviving members of The Doors paid homage to the music's deepest roots while demonstrating their ability to function as an instrumental unit. The blues form provided a natural framework for the kind of improvisational interplay that characterized their work on Full Circle.
