Two-time Grammy Award-winning musician Chuck Mangione, who achieved international success in 1977 with his jazz-flavored single “Feels So Good” and later became a voice actor on the animated TV comedy “King of the Hill,” has died. He was 84.

Mangione died at his home in Rochester, New York, on Tuesday in his sleep, said his attorney, Peter S. Matorin of Beldock Levine & Hoffman LLP. The musician had been retired since 2015.

Perhaps his biggest hit — “Feels So Good” — is a staple on most smooth-jazz radio stations and has been called one of the most recognized melodies since “Michelle” by the Beatles. It hit No. 4 on the Billboard Hot 100 and the top of the Billboard adult contemporary chart.

“It identified for a lot of people a song with an artist, even though I had a pretty strong base audience that kept us out there touring as often as we wanted to, that song just topped out there and took it to a whole other level,” Mangione told the Pittsburgh Post-Gazette in 2008.

“He also was one of the first musicians I saw who had a rapport with the audience by just telling the audience what he was going to play and who was in his band,” Mangione told the Post-Gazette.

Mangione earned a bachelor’s degree from the Eastman School of Music — where he would eventually return as director of the school’s jazz ensemble — and left home to play with Art Blakey and the Jazz Messengers.

He donated his signature brown felt hat and the score of his Grammy-winning single “Feels So Good,” as well as albums, songbooks and other ephemera from his long and illustrious career to the Smithsonian’s National Museum of American History in 2009.
