"Machine Gun" is the debut studio album by Commodores, released on July 22, 1974, on Motown Records.

The second single to be released, "I Feel Sanctified", reached number 12 on the "R&B" charts, and concerns a man spiritually blessed by his girlfriend's love. The song has Ronald LaPread on bass guitar, Walter "Clyde" Orange on drums, while Lionel Richie and William King contributed horn arrangements.
