Music can certainly be used to convey a sense of urgency, but we don’t necessarily associate urgency with musicians. Jazz musicians in particular are often stereotyped as hang-loose artistes, wearing frayed shirts and pork-pie hats, following their muses and working late into the night. But as Reese Erlich found out, even in jazz there’s no escaping due dates. Or as famous procrastinator Duke Ellington liked to say, “I ain’t nothin’ without a deadline, baby.”
