Problem: Background: Michael Kevin Taylor (born 17 January 1949) is an English musician, best known as a former member of John Mayall's Bluesbreakers (1966-69) and the Rolling Stones (1969-74). He has appeared on some of the Stones' classic albums including Let It Bleed, Sticky Fingers and Exile on Main St..
Context: After Brian Jones was removed from The Rolling Stones in June 1969, John Mayall recommended Taylor to Mick Jagger. Taylor believed he was being called in to be a session musician at his first studio session with the Rolling Stones. An impressed Jagger and Keith Richards invited Taylor back the following day to continue rehearsing and recording with the band. He overdubbed guitar on "Country Honk" and "Live With Me" for the album Let It Bleed, and on the single "Honky Tonk Women" released in the UK on 4 July 1969.  Taylor's onstage debut as a Rolling Stone, at the age of 20, was the free concert in Hyde Park, London on 5 July 1969. An estimated quarter of a million people attended for a show that turned into a tribute to Brian Jones, who had died two days before the concert.  The Rolling Stones' 1971 release Sticky Fingers included "Sway" and "Moonlight Mile" which Taylor and Jagger had completed in Richards' absence. At the time Jagger stated: "We made [tracks] with just Mick Taylor, which are very good and everyone loves, where Keith wasn't there for whatever reasons ... It's me and [Mick Taylor] playing off each other - another feeling completely, because he's following my vocal lines and then extemporizing on them during the solos." However, Taylor was only credited as co-author of one track, "Ventilator Blues", from the album Exile on Main St. (1972).  After the 1973 European tour, Richards's drug problems had worsened and began affecting the ability of the band to function as a whole. Between recording sessions, the band members were living in various countries and during this period Taylor appeared on Herbie Mann's London Underground (1974) and also appeared on Mann's album Reggae (1974).

Background: Jerry Fulton Cantrell Jr. (born March 18, 1966) is an American musician who is best known as the founder, lead guitarist, co-lead vocalist and main songwriter for the rock band Alice in Chains. The band rose to international fame in the early 1990s during Seattle's grunge movement, and is known for its distinctive vocal style, and the harmonized vocals between Cantrell and Layne Staley (and later Cantrell and William DuVall). Cantrell started to sing lead vocals on Alice in Chains' 1992 EP Sap. After Staley's death in 2002, Cantrell took the role of Alice in Chains' lead singer on most of the songs from the band's two albums without Staley, Black Gives Way to Blue (2009) and The Devil Put Dinosaurs Here (2013), with DuVall harmonizing with him in the new songs and singing Staley's vocals in the old songs.
Context: Cantrell was born in Tacoma, Washington, on March 18, 1966, to Gloria Jean Krumpos and Jerry Fulton Cantrell. He is the oldest of three children. Cantrell's parents divorced when he was seven. His maternal grandmother, Dorothy Krumpos, died of cancer in October 1986, and his mother died of pancreatic cancer at age 43 in April 1987, when he was 21 years old. Friends recalled that Cantrell fell into depression and completely became a different person after losing both his mother and grandmother within a short span of time.  Cantrell noted in an interview that he was "raised on country music" as a youth and that he admires the emotion conveyed in the genre. He also considers himself "half Yankee and half redneck".  However, hard rock music caught Cantrell's interest predominantly, and he bought his first guitar in his mid teens. It would not be until the age of 17 that he began seriously playing the instrument. Cantrell learned to play guitar by ear emulating his idols. He would later cite guitarists such as Jimi Hendrix, Ace Frehley, Tony Iommi, Angus Young, Jimmy Page, Glenn Tipton, K.K. Downing, David Gilmour, Nancy Wilson, and Eddie Van Halen as major influences, as well as Elton John and bands Fleetwood Mac, Heart and Rush as his early songwriting idols.  Cantrell attended junior high and high school in Spanaway, Washington and, before owning his first guitar, was a member of the high school choir which attended many state competitions. In his senior year, Cantrell became choir president, and the quartet sang the national anthem at basketball games and won competitions with the highest marks achievable. Cantrell has cited his interest in dark musical tones as dating back to this period: "In choir we performed a cappella Gregorian chants from the 14th and 15th centuries. It was scary church music." His choir teacher and drama teacher were, early on, his two greatest motivators toward a career in music. When Alice in Chains' first album went gold, Cantrell sent both teachers a gold record.
