The TCB Band is a group of musicians who formed the rhythm section of Elvis Presley's band from August 1969 until his death in 1977 (depending on the context, the nickname may also extend to Presley's background vocalists during that same period: the Imperials, the Sweet Inspirations, and JD Sumner and The Stamps Quartet). The initials TCB stand for Taking Care of Business, a personal motto Presley adopted in the early 1970s. Although personnel changed over the years, the original members were James Burton (lead guitar), Jerry Scheff (bass), John Wilkinson (rhythm guitar), Larry Muhoberac (keyboards) and Ron Tutt (drums). They first appeared live at Presley's first Las Vegas performance at what was then known as the International Hotel (later the Las Vegas Hilton, now Westgate Las Vegas Resort and Casino) on July 31, 1969.

When planning his return to live performing after his successful 1968 NBC television comeback, Presley had to replace original band members Scotty Moore, D.J. Fontana (who had returned to session work) and Bill Black who had formed the Bill Black Combo before his death in 1965.

Presley's first call was to guitarist James Burton, who was from Ricky Nelson's band and a session musician in Nashville and Los Angeles, whom he asked to help form the group after knowing about him for many years and seeing him on television. After keyboardist Glen D. Hardin declined Burton's offer to join the group, Larry Muhoberac, who had played on several of Presley's movie soundtrack sessions, accepted his offer to perform. Burton later added Jerry Scheff on bass and John Wilkinson on rhythm guitar. Muhoberac suggested Ron Tutt for the drums to round out the section. By February 1970, Glen D. Hardin joined on keyboards, replacing Muhoberac who returned to studio work in Los Angeles. (According to Hardin, Muhoberac, "for reasons of his own, didn't want to go on the road anymore.") At that time Bob Lanning, a Los Angeles session drummer joined on drums, briefly replacing Tutt, who had returned by July.

In 1975, Burton, Tutt and Muhoberac backed Johnny Cash on his album, John R. Cash. Before Presley's death in 1977, several current and former members from the TCB Band, initially simultaneously, went on to form the core of Emmylou Harris's Hot Band and later John Denver's band. These musicians included James Burton, Glen D. Hardin, Emory Gordy Jr., and Jerry Scheff. Burton left the Hot Band in early 1976 to focus fully on his work with Presley and the TCB Band, and he was replaced in the Hot Band by English guitarist Albert Lee. (Scheff was never a member of the Hot Band.) Hardin left the TCB Band in early 1976 to work full-time with Emmylou Harris, and he was replaced by Tony Brown. Larrie Londin, a Nashville session drummer who recorded and occasionally toured with Presley over a nine-year period, filled in for Tutt on occasion during 1976 and 1977 performances.

Before Presley's death in 1977, several former members from the TCB Band went on to form Emmylou Harris's Hot Band and the John Denver Band. These musicians include James Burton, Glen D. Hardin, Emory Gordy Jr. and Jerry Scheff. Burton left the Hot Band in 1976 and was replaced by English guitarist Albert Lee. Scheff was never a member of the Hot Band. Gordy left John Denver's band in 1980 (before rejoining briefly in 1989 and once again in 1991) and was replaced by Scheff. Burton, Hardin, and Scheff remained in John Denver's band until early 1994.

After drumming a few years with the Jerry Garcia Band before Presley's death, Ron Tutt was invited by Neil Diamond to become Diamond's permanent concert and recording session drummer. Tutt's drumming has since become a feature to Diamond's concert shows, punctuating moments in the Diamond concert with his TCB Band style drum fills and cymbal crashes. Tutt is a workman celebrity drummer, and routinely receives concert crowd ovations when he appears and takes his seat at his drum kit. Noteworthy during concerts is Tutt's soaring drum work on the song, "Holly Holy". Tutt recorded and toured with Diamond until Diamond's retirement from touring after he was diagnosed with Parkinson's disease.

Tutt also appears on several of recordings by Nancy Sinatra.

The TCB Band reunited with a new lineup to record their own album in 1979 of covers of Elvis Presley songs as a tribute. They also reunited in 1981 as the backing band for Tony Sheridan, augmented by Klaus Voormann and again mostly featuring Sheridan's recordings of Elvis Presley songs.^{[citation needed]}
