The centerpiece of tonight's Sonic Evolution concert at Seattle Symphony is a requiem for Kurt Cobain by the man who wrote a soft-rock love letter to Sheena Easton on his last album, William Brittelle.

The whole night is intended to draw out new composers based on the classic (but not classical) sounds of Seattle—meaning, of course, Jimi Hendrix and Kurt Cobain. Hey Marseilles open things up, and are followed by four world premieres: Vladimir Nikolaev's The Sinewaveland: Homage to Jimi Hendrix, Seattle jazz trumpeter Cuong Vu's ONE, and Phillip A. Peterson's Savana, with Brittelle's Cobainiana. All conducted by Ludovic Morlot.

Sonic Evolution starts at 7:30, tickets are here.
