Mark Knopfler plays Sultans of Swing entirely with his fingers — no pick — producing a warm, articulate tone that no other guitarist has fully replicated. The closing solo builds from understated jazz-inflected phrases into a climactic run that seems to narrate the story of the fictional band the song describes. Knopfler wrote the song after watching a pub jazz band in London, and the guitar work captures that intimate, smoky atmosphere perfectly.
