This recording of "Tune Up" comes from Stephen Riley's 2007 album Once Upon a Dream. Attributed to Miles Davis, though its authorship has been disputed with some crediting the composition to pianist Eddie Vinson, "Tune Up" is a compact 16-bar form built on a descending sequence of ii-V-I progressions that has become one of the most commonly played tunes at jazz jam sessions and on bandstands worldwide. Riley attacks it at a scorching 344 BPM, launching into a monumental nineteen-chorus tenor saxophone solo that stands as the most expansive improvisation on the album. At this extreme tempo, the demands on technique, endurance, and creative imagination are immense, and Riley meets them head-on, sustaining musical interest across what amounts to more than two and a half minutes of continuous soloing over the rapid-fire chord changes. His Lester Young-rooted style proves remarkably adaptable to this high-velocity context, as his lines maintain their characteristic melodic logic and rhythmic poise even at breakneck speed. As the sole soloist on the track, Riley shoulders the entire performance, building waves of intensity that crest and recede across the many choruses. The recording is a tour de force of modern mainstream jazz tenor playing, demonstrating both physical stamina and artistic depth.
