"C.O.W.L." launched back in May at Image Comics with the creative team of co-writers Kyle Higgins and Alec Siegel and artist Rod Reis. The series focuses on a superhero union in early 1960s Chicago, with a mood that reflects the era -- and now, songs to go along with it.

"The C.O.W.L. Sessions" is a jazz soundtrack based on the comic book series, set for a digital release this coming Tuesday, Oct. 28 -- a day before the release of the first "C.O.W.L." -- which stands for Chicago Organized Workers League -- collection, "Principles of Power." The album features original music composed by Joe Clark, someone who shares a long history with Higgins.

"In many ways, 'The C.O.W.L. Sessions' has been in the works for almost 15 years, from the day Joe and I met in high school jazz band," Higgins said in a press release. "Of course, we had no idea our collaboration was going to take this form -- his album inspired by my crime-noir-superhero-comic -- but considering we became friends over our mutual love of jazz, Chicago, film, and comics, I can't think of anything more fitting."

The nine-track "C.O.W.L. Sessions" will be released by the Sparks & Shadows label, founded by noted "Battlestar Galactica," "The Walking Dead" and "Marvel's Agents of S.H.I.E.L.D." score composer Bear McCreary. It's the first album from the label not composed by McCreary himself. "Joe Clark's original score for the comic book 'C.O.W.L.' was the perfect choice for our first release of music other than my own, because he perfectly captured the moody, sexy energy of the retro/noir stories," McCreary said in a statement.

A multimedia approach fits right with "C.O.W.L." history, as the series has its earliest roots in "The League" -- a college thesis film co-written by Higgins and Siegel that helped get them their first work in the comic book industry.

CBR has the exclusive debut of the video trailer for "The C.O.W.L. Sessions," featuring both scenes from the comic book and live-action shots, set to a "C.O.W.L."-specific version of Fred Fisher's 1922 song "Chicago (That Toddlin' Town)."
