The album 'Guess Who' was released in 1972 by ABC Records, produced by Ed Michel. It features a notable collaboration with saxophonist Eddie 'Cleanhead' Vinson, who also contributes vocals on some tracks.
Recorded in Los Angeles, the album showcases B.B. King exploring a more funk and soul-oriented sound, with string and horn arrangements reflecting early 1970s musical trends.
The album reached number 21 on the Billboard R&B Albums chart and number 110 on the Billboard 200, solidifying King's versatility during that decade.
