Denis Leary is back in business with FX, setting a deal for a half-hour comedy pilot about a washed-up rock musician trying to revive his career.

Leary wrote the “Sex&Drugs&Rock&Roll” pilot and will star as lead character Johnny Rock. FX Prods. and Fox TV Studios are set to produce the single-camera comedy pilot in the spring.

Deal reunites Leary with FX, where he spent seven seasons as the star and co-creator of “Rescue Me,” in which he played a conflicted New York City firefighter struggling with demons after 9/11.

“Denis is a tremendous talent who played a major role in the growth of our network with ‘Rescue Me,’ which was one of the most groundbreaking series of the last decade,” FX Prods. chief Eric Schrier.

Leary and his longtime producing partner Jim Serpico are exec producers for their Apostle Pictures banner.

“I am very excited to be returning to FX where working with (FX execs) Nick (Grad), Eric and John Landgraf has been one of the best creative experiences of my life,” Leary said. “Plus I hear they have much better swag now,” Leary said.

Apostle is also working with Fox TV Studios on a comedy series for USA Network, “Sirens,” set to bow March 6.
