Jailbreak

The title telegraphs freedom but the track delivers something more ambiguous — a minor-key gallop that gives Lynott's outlaw narrative an underlying edge of desperation. The twin guitars arrive locked in harmony, Steve Gorham and Brian Robertson playing lines that chase each other like pursued men. Lynott's vocal is tighter here than on the band's more celebratory material, the swagger compressed by urgency. The song belongs to the tradition of outlaw ballads — Jesse James, Folsom Prison — refracted through Dublin rock's particular sensibility, a culture simultaneously romanticizing and suspicious of transgression. The production is lean: everything serves the drive. It became one of the defining live tracks of the era, a crowd-ignition device that still works whenever played. The lyric's final ambiguity — does the escape succeed? — gives it a resonance pure triumph wouldn't.
