Gwilym Simcock, 27, dazzling poet of the keyboard and Radio 3 New Generation Artist, has been catapulted from basement-club obscurity to Saturday night Proms stardom. As Jamie Cullum urged recently: "Catch Gwilym while you can still see him in venues without ushers".

Too late. The Albert Hall Red Coats were out in force.

In a weekend packed with premieres, Simcock's Progressions wins the prize for enlightened commissioning. This half-hour work combines the BBC Concert Orchestra with his own inspirational trio: Phil Donkin double bass, Martin France drums and Simcock himself. A stiffly traditional sounding piano concerto morphs into a noisy, rhythmically rich climax with extended improvisations and a short, bullet-shot ending. Orchestral colour is subtle and adroit, though tightening some swoony string passages would add muscle.

The mostly American programme concentrated on Gershwin, with a floaty arrangement of My Man's Gone Nowby Jason Yarde and his own short, amiable BBC Commission. Stravinsky's Ebony Concerto, an ever-astonishing masterpiece, with clarinettist Michael Collins as stylish soloist, provided the gold standard.

The BBC Concert Orchestra (a conspicuously smiling band) is throwing off its Cinderella reputation. Conductor Charles Hazlewood brings nimble, bandleader incisiveness and beady eclecticism. Forget whether or not it's jazz, one of those red-rag words to the classically timorous. Can we just call it music?
