Legendary Jazz musician, composer, and King of the Hill regular Chuck Mangione has died at 84.

TMZ reported on the famous brass artist’s passing today, saying that he died of natural causes in his Rochester, New York, home. The Bartolomeo & Perreto Funeral Home adds (via RochesterFirst) that Mangione died in his sleep Tuesday.

Mangione’s career in music traces back to the 1960s, where he managed to kick off his life as a professional musician alongside his brother, Gap, with records like Hey Baby! and Spring Fever. Mangione emerged as one of the most notable, recognizable jazz musicians of the century thanks to ‘70s hits like Give It All You Got, Bellavia, and, most famously, Feels So Good.

Feels So Good is no doubt the Grammy-winning flugelhorn player’s biggest song, coming in as his most-listened-to track at more than 21.7 million plays on Spotify. Since its 1978 debut, the track has been featured in Friends, Zombieland, South Park, Doctor Strange, Life After Beth, and so much more.

Jazz isn’t quite the mainstream success it was 50 years ago, but Mangione still managed to find his way to the public eye despite letting his jazz playing do the talking for decades. While he guest-starred in projects like Magnum, P.I., as well as Canadian children’s television series Sharon, Lois & Bram’s Elephant Show in the ‘80s, it’s King of the Hill that might be his crowning achievement in terms of on-screen work.

Mangione appeared in multiple episodes of Mike Judge and Greg Daniels’ classic Texas-set show, showing up as a spokesperson for the fictional superstore, Mega Lo Mart. It was a recurring role that put jazz front and center, sneaking in references to tracks like Feels So Good while giving him a speaking role on more than one occasion.

It’s unclear if Mangione returned to play any kind of role in Hulu’s King of the Hill revival, which is slated to premiere August 4, 2025. In the meantime, fans of his work have taken to social media to celebrate his life and mourn his passing with segments of his music and highlights from his appearances on the show.
