Machine Gun Etiquette featured 1960s garage-rock influence

Machine Gun Etiquette (1979) featured a strong 1960s garage-rock influence with a Farfisa organ on several songs. Recording at London’s Wessex Studios at the same time as the Clash were there to record London Calling (1979), Joe Strummer and Mick Jones made an uncredited vocal appearance on the title track. Machine Gun Etiquette (1979) received largely positive reviews; Ira Robbins and Jay Pattyn of Trouser Press described it as “a great record by a band many had already counted out.”
