Ozzy Osbourne left behind a very heavy legacy. Here's a look at his best songs, from Black Sabbath's "Paranoid" to "Crazy Train" and "Mr. Crowley."

Black Sabbath, the band that Osbourne famously fronted, played their first U.S. gig at Rowan University. The school shared a flier from the band's inaugural stop in the states and a cheeky story about the gig. Black Sabbath played their first U.S. gig on Oct. 30, 1970 at the then-Glassboro State University.

Osbourne died on Tuesday at 76, just weeks after he and Black Sabbath performed at their farewell Back to the Beginning concert earlier in July.
