Final answer:
Jimi Hendrix performed a cover of 'Sgt. Pepper's Lonely Hearts Club Band' two days after the Beatles' album release, showing his exceptional musical abilities and reverence for the band.
Step-by-step explanation:
The artist who famously played a tribute to the Beatles by performing a cover of 'Sgt. Pepper's Lonely Hearts Club Band' just two days after its release was Jimi Hendrix. Hendrix, an American rock guitarist, showcased his admiration for the Beatles by doing an impromptu performance of the title track during a concert at the Saville Theatre in London on June 4, 1967. The Beatles album was released on June 1, 1967, making this performance quite notable for its quick turnaround and Hendrix's talent to learn and reinterpret the song in such a short span of time.
