Spirit Catalogue Holdings, the parent company of Spirit Music Group, has acquired a majority interest in the publishing rights of legendary record producer James William Guercio. As part of the deal Spirit also acquired a significant stake in Guericio's producer royalties.

The deal includes a decade's worth of music recorded by Chicago through the 1970's, as well as Guercio's work with the Buckinghams. Additionally, Spirit will participate via producer royalties in Blood Sweat & Tears' eponymous 1969 breakthrough album, which includes "You've Made Me So Very Happy", "And When I Die" and "Spinning Wheel."

Spirit will roll out an extensive synchronization plan to revitalize the
Guerceio affiliated songs and recordings into film, television, advertising, video games and a wide range of new media along with the reinvention of classic tracks through re-mixes, samples and covers.

In addition, Spirit plans to work with the still-active producer in telling the story of the Caribou Ranch recording studio, which is situated on more than 4,000 acres in Colorado's Rocky Mountains. In addition to five multi-platinum albums by Chicago, other albums recorded there include Steven Stills' "Manassas," Earth Wind & Fire's "That's The Way Of The World," Supertramp's "Even In The Quietest Moments," Nitty Gritty Dirt Band's "Stars & Stripes Forever," and Elton John classics Caribou, Captain Fantastic & The Brown Dirt Cowboy and Rock Of The Westies.
