The Last of the Red Hot Burritos is the fourth and final album by the original incarnation of country rock group The Flying Burrito Brothers, released in 1972. By the time this album was recorded, "Sneaky" Pete Kleinow and Bernie Leadon had left the band, leaving Chris Hillman as the sole founding member. In their places, Hillman recruited Al Perkins and Kenny Wertz respectively. The band also added two new musicians in Byron Berline and Roger Bush. This lineup toured until Hillman left the band in October 1971, leaving the rights to the band’s name to Rick Roberts. Once Hillman departed, A&M Records lost faith in the group. Instead of allowing a Roberts-led version of the band (with no founding members) to record a new studio album, A&M released this live recording instead which fulfilled the band’s contract and they were subsequently dropped from the label.
A group of Burritos led by Rick Roberts would continue to tour Europe with no original members until 1973 (to meet contractual obligations), at which point the band was officially dissolved by Roberts, bringing the Flying Burrito Brothers to an end.
