Joe Bonamassa (born May 8, 1977) is an American blues rock guitarist and singer.

His most recent album, Driving Towards The Daylight, reached #2 on the U.K. Top 40 Albums Chart, and he completed an arena tour there in 2012. In 2009 he was the recipient of the Classic Rock Magazine "Breakthrough Artist of the Year" award, and The Guardian said of him: "the 32-year-old from upstate New York has consolidated a reputation as the pre-eminent blues-rock guitarist of his generation".

Beth Hart (born January 24, 1972) is an American singer who became famous with the hit "LA Song (Out of This Town)", which aired during Episode 17 of the 10th and final season of Beverly Hills, 90210.

Her musical influences include rock, blues, gospel, jazz, and classical.

While playing the Los Angeles clubs, she enlisted bassist Tal Herzberg and guitarist Jimmy Khoury. In 1993, Hart appeared on Ed McMahon's Star Search several times.

"Beth Hart and the Ocean of Souls" was recorded in 1993. It includes "Am I the One" (re-worked on later album Immortal (1996)) and a pop-rock cover of the Beatles' "Lucy in the Sky with Diamonds."

Hart released her album Immortal with her band Beth Hart Band in 1996.

Terence William 'Blondie' Chaplin is a musician from Durban, South Africa who first became known to international audiences through his brief stint in the early 1970s as a singer and guitarist for The Beach Boys. Chaplin was also listed as a co-producer, sang lead vocals with fellow South African musician Ricky Fataar (drummer) and composed, with Fataar, "Here She Comes" and "Hold On Dear Brother" on the twenty-third official Beach Boys album, Carl and the Passions - "So Tough", released in 1972. He is well known in recent years as a long term backing vocalist, percussionist and acoustic rhythm guitarist for the Rolling Stones on their tours.

Blondie Chaplin, along with drummer Ricky Fataar, joined the Beach Boys when original drummer Dennis Wilson suffered a hand injury which left him unable to play the drums for almost two years. For the Beach Boys, it was a period in which long-time member Bruce Johnston had departed the band, and one-time leader Brian Wilson's participation in the group was very limited. As a result, Chaplin and Fataar joined the Beach Boys as full-fledged members and not merely as backing musicians. Chaplin left the group in 1973 after a dispute with the Beach Boys' management; Fataar remained with the band until the following year (and has performed with Bonnie Raitt's band since the 1980s).
