Tomorrow is Jimmy Rowles's 99th birthday anniversary. The Spokane, Washington, native was quirky, unpredictable, and utterly compelling, making even the most hackneyed standard sound fresh, alive, and better than you'd remembered it. He had a unique harmonic sense that left plenty of room for surprise. He's reputed to have known more tunes than anyone else in the business, and he knew potential when he heard it. Diana Krall took lessons with him in 1983 before she enrolled at Berklee, and he (and bassist Ray Brown) encouraged her to sing.
