The J.B.'s was the name of James Brown's band from 1970 through the early 1980s.
The J.B.'s were formed in March 1970 after most of the members of Brown's previous band walked out on him over a pay dispute.
The J.B.'s initial lineup included bassist William "Bootsy" Collins and his brother, guitarist Phelps "Catfish" Collins; Bobby Byrd (organ), and John "Jabo" Starks (drums), both holdovers from Brown's 1960s band; three inexperienced horn players, Clayton "Chicken" Gunnells, Darryl "Hasaan" Jamison, and Robert McCollough; and conga player Johnny Griggs.
This version of the J.B.'s played on some of Brown's most intense funk recordings, including "Get Up (I Feel Like Being a) Sex Machine", "Super Bad", "Soul Power", and "Talkin' Loud and Sayin' Nothing".
In December 1970, trombonist Fred Wesley rejoined James Brown's organization to lead the J.B.'s. Other former Brown sidemen, including Maceo Parker and St. Clair Pinckney, eventually followed his lead, while the Collins brothers and most of the rest of the "original" J.B.'s left Brown to join George Clinton's Parliament-Funkadelic collective.
