First State Ballet Theatre’s world premiere of “Irene” on Feb. 21 tells the story of a young dancer who joins a new company—made up of vampires. It’s a collaboration between Wilmington guitarist-composer Shaun Dougherty and original choreography by FSBT’s Alex Buckner, making it all Delaware. “‘Irene’ is edgy, urban, exciting and up to the minute with live music,” says FSBT executive director Robert Grenfell. “The pit band and conductor, hand-picked by the composer, Shaun, will feature a full string section, jazz guitar, grand piano and percussion.”(658-7897, firststateballet.com)
