PEORIA — A popular Peoria radio personality had his last day on the air Tuesday morning.

Marc Alghini, the program director and morning host at 99.9 WWCT, was not heard on his customary early morning time slot Wednesday after departing from the radio station. Alghini did not comment beyond saying that the separation was mutual over "philosophical differences."

Mike Rea, general manager of Advanced Media Partners, which runs several radio stations in Peoria, also declined to comment on Alghini's departure apart from confirming that he was no longer with the station.

Chris Watters has stepped in as the interim morning host alongside Roxy Baker, who co-hosted with Alghini for the last several years.

Under Alghini's tenure as program director, WWCT billed its programming as "world class rock," broadcasting rock tunes from the past and present while showcasing up-and-comers. It also initiated a variety of unique live performances around the Peoria area, including intimate shows at bars such as The Fieldhouse, Pour Bros. and W.E. Sullivan's as well as multi-act bills for the annual Snowball concert in the winter.

Though Alghini's fingerprints will no longer be on those shows, Rea did not forecast any alterations to WWCT's programming.

"The format and the philosophy of the station won't change," Rea said.

Alghini arrived in Peoria in the summer of 2013 after a stint at Chicago's renowned rock station WXRT. He was a familiar presence at events all around central Illinois, whether it was at the Riverfront Museum, a summer festival or emceeing a fundraiser. Former Peoria assistant city manager Chris Setti, who was in charge of economic development, referred to Alghini as a "force for good for the city of Peoria."

Rea said that the search for Alghini's replacement as the program director is already underway.
