The core of the band is Glen Galaxy (former Trumans Water member, Glen Galloway). Other members include Slo-Ro, Brian Cantrell, Micah Ortega, Ron Easterbrooks, Jon Galaxy and Nathan Poage. Many others are credited per album or track. The first Soul-Junk release was called ''1950''. Its name was derived from the musical style of the era, a fusion of rock and free jazz. Subsequent albums have been numbered up from 1950; Extended Play releases have been numbered down. Soul-Junk songs have also been released on innumerable compilations.
