Funk and pop saxophonist Jimmy Castor died today at 2:30 p.m. in Las Vegas from causes that are currently unknown. He was 64.

While he had several notable hits, it was his 1972 single, "Troglodyte (Cave Man)," that had the most success. It's been certified gold by the RIAA and, in terms of more current music, has been sampled by a slew of hip-hop acts.

N.W.A. used it on two different tracks, "Gangsta Gangsta" and "The Dayz of Wayback," and Audio Two had it on the DJ Clark Kent mix of "Top Billin'."

Most recently, you probably heard Castor's "I Just Wanna Stop" on Kanye West's "We Don't Care" off his debut, The College Dropout.

There isn’t any easy way to explain how much influence Jimmy Castor has had on music, tangible or otherwise. But it’s important to frame Castor outside the novelty of “Bertha Butt Boogie.” Castor put the fun in funk, and pioneered a dense, full-throttle style.
