Background: Charles Michael "Chuck" Schuldiner (May 13, 1967 - December 13, 2001) was an American singer, songwriter, and guitarist. He founded the pioneering band Death in 1983. Schuldiner is often referred to as "The Godfather of death metal", and his obituary in the January 5, 2002 issue of UK's Kerrang! magazine said that "Chuck Schuldiner was one of the most significant figures in the history of metal."
Context: Schuldiner formed Death as Mantas in 1983 when he was just 16 years old. Original members were Schuldiner (guitar), Rick Rozz (guitar) and Kam Lee (drums and vocals). In January 1986, Schuldiner moved to Toronto and temporarily joined the Canadian band Slaughter. However, he quickly returned to continue the formation of Death. Death underwent many lineup changes. With Chris Reifert, Schuldiner eventually released the first Death album, titled Scream Bloody Gore, in 1987. He continued with 1988's Leprosy with the line-up of former Mantas guitarist Rick Rozz and rhythm section Terry Butler on bass and Bill Andrews on drums, and 1990's Spiritual Healing, where guitarist James Murphy had replaced the fired Rozz in 1989. After Spiritual Healing, Schuldiner stopped working with full-time band members, preferring to work with studio and live venue musicians, due to bad relationships with Death's previous rhythm section and guitarists. This earned Schuldiner something of a 'perfectionist' reputation in the metal community. Schuldiner had also fired his manager Eric Greif but settled and re-hired him before the recording of his next, influential release. Death's breakthrough album, Human saw the band evolving to a more technical and progressive style, in which Schuldiner displayed his guitar skills more than ever. He continued in this style (and continued the success of the band) with 1993's Individual Thought Patterns, 1995's Symbolic, and finally The Sound of Perseverance in 1998. Throughout his career, Schuldiner was not afraid to take on controversial lyrical subjects, taking an anti-drug stance on "Living Monstrosity" and writing about abortion in "Altering the Future". He put Death on hold after this to continue Control Denied, which he had been putting together prior to the release of The Sound of Perseverance, and released The Fragile Art of Existence in 1999. Control Denied also had other players from the latest Death album but featured a melodic metal vocalist. Schuldiner also played guitar in the "supergroup" Voodoocult on the album Jesus Killing Machine in 1994 and played a guest solo on Naphobia's 1995 release, Of Hell on the track "As Ancients Evolve" as a favor to the band's bassist at the time who was a friend of Schuldiner's. Schuldiner was also asked to be one of the many guest vocalists on Dave Grohl's 2001 Probot. Grohl, Napalm Death, Ozzy Osbourne, and Anthrax all increased efforts to raise funds for Schuldiner's medical bills with Grohl trying to involve Schuldiner on an album he was working on. In a 1999 interview Schuldiner spoke about why he didn't sing on the album The Fragile Art of Existence "...these vocals are all I ever wanted to do in Death but couldn't. I've had this dream of recording like that for years, and it seems like a dream come true. Tim Aymar is an amazing singer and this is the main difference. I think people will be surprised at the violence and strength of the album. Many people are expecting something like Iron Maiden, but, despite being one of my favorite bands, I didn't want to make an Iron Maiden-like album. I wanted to make an unpredictable album, just like I did in Death, I guess. I don't like to make predictable albums."
Question: Were they performing live at that time?

Problem: Background: The Funk Brothers were a group of Detroit-based session musicians who performed the backing to most Motown recordings from 1959 until the company moved to Los Angeles in 1972. They are considered one of the most successful groups of studio musicians in music history. The Funk Brothers played on Motown hits such as "My Girl", "I Heard It Through the Grapevine",
Context: In February 2004, surviving members of the Funk Brothers were presented the Grammy Legend Award at the 46th Annual Grammy Awards at the Staples Center in L.A. In March 2006, some remaining Funk Brothers were invited to perform on Philadelphia writer-producer-singer Phil Hurtt's recording session at Studio A, Dearborn Heights, Detroit, where they contributed their performances to "The Soulful Tale of Two Cities" project. The double-album sleeve notes read: "Motown's legendary Funk Brothers and members of Philadelphia's world renowned MFSB take you 'back in the day' with an album filled with classic Philly and Motown hits." Bob Babbitt, Joe Hunter, Uriel Jones, and Eddie Willis performed alongside other notable Detroit session musicians, like Ray Monette, Robert Jones, Spider Webb, and Treaty Womack. The musicians played on the Philly hits, giving their unique Detroit interpretations of the songs under the leadership of Phil Hurtt, Bobby Eli, Clay McMurray and Lamont Dozier. Many other ex-Motown and Detroit artists performed vocals on the session, including the Velvelettes, Carolyn Crawford, Lamont Dozier, Bobby Taylor, Kim Weston, Freda Payne, and George Clinton. In 2008 Uriel Jones, Ray Monette, Dennis Coffey, Robert Jones and Bob Babbitt accompanied other notable Detroit session musicians, including Larry Fratangelo, Dennis Sheridan, Edward Gooch, John Trudell, saxophonist George Benson, Mark Burger, David Jennings, Spider Webb, and Rob Pipho, on the Carl Dixon Bandtraxs project, which featured a Dennis Coffey-Carl Dixon production of four new songs. Vocal performances by Spyder Turner, Pree and Gayle Butts provided lead and backing for the session. The session was arranged by ex-Motown arranger David J. Van De Pitte. The session was also at Studio A, Dearborn Heights, Detroit, and was the dream of a 19-year-old Dixon, back in 1974, to pay homage to musicians, particularly the Funk Brothers, producers and those who influenced him with their music. It took Dixon almost 33 years to find the musicians and meet some of them on the web site soulfuldetroit.com. It was via this web site that he and Dennis Coffey hooked up and then eventually collaborated to make the session work. In 2008 surviving members recorded Live in Orlando, an album and video. In 2010, surviving members of the Funk Brothers accompanied Phil Collins on his Motown covers album, Going Back, and appear in the live Going Back concert DVD.
