Power trio in the context of Guitar solo

A backing vocalist is a singer who provides vocal harmony with the lead vocalist or other backing vocalists. A backing vocalist may also sing alone as a lead-in to the main vocalist's entry or to sing a counter-melody. Backing vocalists are used in a broad range of popular music, traditional music, and world music styles.

Solo artists may employ professional backing vocalists in studio recording sessions as well as during concerts. In many rock and metal bands (e.g., the power trio), the musicians doing backing vocals also play instruments, such as guitar, electric bass or keyboards. In Latin or Afro-Cuban groups, backing singers may play percussion instruments or shakers while singing. In some pop and hip-hop groups and in musical theater, they may be required to perform dance routines while singing through headset microphones.

Eric Patrick Clapton (born 30 March 1945) is an English rock and blues guitarist, singer, and songwriter. He is regarded as one of the most successful and influential guitarists in rock music. Clapton ranked second in Rolling Stone's list of the "100 Greatest Guitarists of All Time" and fourth in Gibson's "Top 50 Guitarists of All Time". He was named number five in Time magazine's list of "The 10 Best Electric Guitar Players" in 2009.

After playing in a number of different local bands, Clapton joined the Yardbirds from 1963 to 1965, and John Mayall & the Bluesbreakers from 1965 to 1966. After leaving Mayall, he formed the power trio Cream with drummer Ginger Baker and bassist/vocalist Jack Bruce, in which Clapton played sustained blues improvisations and "arty, blues-based psychedelic pop". After four successful albums, Cream broke up in November 1968. Clapton then formed the blues rock band Blind Faith with Baker, Steve Winwood, and Ric Grech, recording one album and performing on one tour before they broke up. Clapton then toured with Delaney & Bonnie and recorded his first solo album in 1970, before forming Derek and the Dominos with Bobby Whitlock, Carl Radle and Jim Gordon. Like Blind Faith, the band only lasted one album, Layla and Other Assorted Love Songs, which includes "Layla", one of Clapton's signature songs.

Motörhead (/moʊtəhɛd/ mo-TAH-head) were an English rock band formed in London in 1975 by bassist and lead vocalist Lemmy Kilmister, guitarist Larry Wallis and drummer Lucas Fox. Kilmister was the primary songwriter and only constant member. The band are often considered a precursor to the new wave of British heavy metal, which re-energised heavy metal in the late 1970s and early 1980s. Though several guitarists and drummers played in Motörhead, most of their best-selling albums and singles featured drummer Phil "Philthy Animal" Taylor and guitarist "Fast" Eddie Clarke. From 1995 until the band's break-up in 2015, the group consisted of Kilmister, guitarist Phil Campbell and drummer Mikkey Dee.

Motörhead released 22 studio albums, 10 live recordings, 12 compilation albums and five EPs over a career spanning 40 years. Usually a power trio, they had particular success in the early 1980s with several successful singles in the UK Top 40 chart. The albums Overkill, Bomber (both 1979), Ace of Spades (1980) and, particularly, the live album No Sleep 'til Hammersmith (1981) cemented Motörhead's reputation as a top-tier rock band. The band are ranked number 26 on VH1's 100 Greatest Artists of Hard Rock. In 2016, the staff of Loudwire named them the eighth-best metal band of all time. As of 2025, the band have sold more than 25 million albums worldwide.

William Rory Gallagher (/ɡæləhər/ GAL-ə-hər; 2 March 1948 – 14 June 1995) was an Irish musician, singer, and songwriter. Regarded as "Ireland's first rock star", he is known for his virtuosic style of guitar playing and live performances. He has sometimes been referred to as "the greatest guitarist you've never heard of".

Gallagher gained international recognition in the late 1960s as the frontman and lead guitarist of the blues rock power trio Taste. Following the band's break-up in 1970, he launched a solo career and was voted Guitarist of the Year by Melody Maker magazine in 1972. Gallagher played over 2,000 concerts worldwide throughout his career, including many in Northern Ireland during the Troubles. He had global record sales exceeding 30 million.

Grand Funk Railroad (often shortened to Grand Funk) is an American rock band formed in Flint, Michigan in 1969 by Mark Farner (vocals, guitar, keyboards, harmonica), Don Brewer (drums, vocals) and Mel Schacher (bass). The band achieved peak popularity and success during the 1970s with hit songs such as "We're an American Band", "I'm Your Captain (Closer to Home)", "Some Kind of Wonderful" (a cover of Soul Brothers Six), "Walk Like a Man", "The Loco-Motion" (a cover of Little Eva), "Bad Time" and "Inside Looking Out" (a cover of the Animals). Grand Funk released six platinum and seven gold-certified albums between their recording debut in 1969 and their first disbandment in 1976.

Known for a crowd-pleasing arena rock style, the band toured extensively and played to packed arenas worldwide, and was well-regarded by audiences despite a relative lack of critical praise. The original trio reunited at various times later into the band's career; after Farner's final departure in 1998, Brewer and Schacher have continued touring as Grand Funk Railroad.
