Why was Ozzy osbourne considered controversial?

Answer 1

where do I begin, lets start with what we know

he bit the head off a bat in a live concert

he bit the head off a few doves in CBS records

he urinated on the Alamo which banned him from Texas for a while

he almost strangled his wife to death (forget why but he was drunk/high)

singing about Alistar Crowly, Charlie Manson and so on

with black sabbath their image and sound was ahead of its time they where labeled as devil worshippers, singing about darker topics than sunshine and love. This would have happened to you or I back in the day too, but they where one of the first successful bands to sing about this.

when he was solo a song called "suicide solution" before or during the guitar solo you hear Ozzy saying something incomprehensable that sounds like get the g.... shoot , but they where just messing with the recording to get a unique sound and the case would be later dropped, Judas Priest on the other hand wasn't so lucky.

all in all as long as he continues to make great music I'm buying tickets and albums to support the man.
