R.I.P. funk musician Jimmy Castor

Funk musician Jimmy Castor, whose run of hits in the '70s laid down grooves that were re-purposed in rap songs decades after his commercial prime, died Monday in Las Vegas. The cause of death is unknown. He was 64.
Castor's biggest hits include the primordial soul of 1972's million-selling single "Troglodyte (Cave Man)" and "It's Just Begun," the latter of which is the title track of his most successful album. But Castor might be better known by the artists that have sampled his work, including N.W.A.—who sampled "Troglodyte" on both "Gangsta Gangsta" and "The Dayz Of Wayback"—and Kanye West, who borrowed from Castor's "I Just Wanna Stop" for "We Don't Care" from The College Dropout. "It's Just Begun" is in its own category as a heavily sampled classic, becoming one of the most used breaks for break-dancers at the dawn of the hip-hop era.
