Paul Charles Caravello (July 12, 1950 – November 24, 1991), also known as Eric Carr, was an American musician, best known as drummer for the rock band Kiss. Caravello was selected as the new Kiss drummer after Peter Criss left in 1980, where he took up the "Fox" persona. He remained a band member until his death of complications from heart cancer in November 1991, aged 41. Caravello was an artist and went to the High School of Art & Design in New York City.

Caravello played with a string of bands mostly performing covers of well-known songs before joining Kiss. The first band, "The Cellarmen", was formed in 1965 by him and a couple of friends. They started playing local clubs in Brooklyn and Queens. Only a handful of recordings were made, released on the "Jody" label, a small Brooklyn recording studio. Caravello then joined a band called "Things That Go Bump In The Night" and later "Smack", the latter of which consisted mostly of members from "The Cellarmen", who disbanded in 1968.

"Salt & Pepper" was Caravello's next cover band, playing music from multiple genres. He would go on with this band for nine years. The band enjoyed some success, performing as opening act for established names such as Stevie Wonder and Nina Simone. Changing name to "Creation" in 1973, the band was now performing disco music. Tragedy struck when a fire broke out during a discothèque gig in Port Chester, New York, killing dozens of people including the band's keyboardist and lead singer. Caravello escaped and was credited with saving another person. It was determined that the fire had been started by a thief in an adjacent building hoping to cover his tracks. The band continued for some time, sometimes using the name "Bionic Boogie".
