The entire music world is mourning the loss of electric guitar pioneer Eddie Van Halen, who has lost his longtime battle with cancer, passed away at St. Johns Hospital in Santa Monica today. He was 65 years old.

A person close to Van Halen’s family confirmed the rocker died Tuesday due to cancer. The person was not authorized to publicly release details in advance of an official announcement.

With his distinct solos, Eddie Van Halen fueled the ultimate California party band and helped knock disco off the charts starting in the late 1970s with his band’s self-titled debut album and then with the blockbuster record “1984,” which contains the classics “Jump,” “Panama” and “Hot for Teacher.”

Van Halen is among the top 20 best-selling artists of all time and the band was inducted into the Rock and Roll Hall of Fame in 2007. Rolling Stone magazine put Eddie Van Halen at No. 8 in its list of the 100 greatest guitarists.

Van Halen also played guitar on one of the biggest singles of the 1980s: Jackson’s “Beat It.” His solo lasted all of 20 seconds and took only a half an hour to record. He did it as a favor to producer Quincy Jones, while the rest of his Van Halen bandmates were out of town.
