This whole lack of respect thing reminded of something I read recently about Dave Grohl paying hommage to Dimebag Darrell...
" There was an Ozzfest in England in 1998, and Korn canceled. So we got the call. It was Slayer, Pantera and Black Sabbath. We had to go on after Pantera. I was so terrified: ‘There’s gonna be a riot. I’m gonna get drawn and quartered. No one’s going to like our band.’
But we played, and I looked to the side. The guys from Pantera are watching us and singing the lyrics to our songs. Afterwards we made friends with Pantera. I was nervous and scared; I didn’t think I fit in. But they were so open to us. That backstage hospitality we try to have – it all came from Pantera. Dimebag Darrell was the nicest f–king guy in the world. He could walk in and do a shot of Crown Royal with Justin Bieber, with Rick Nielsen, with James Brown – he was everybody’s best friend. And you could feel that energy when he was playing.
After that day, I was like, ‘From now on, everybody’s allowed in this room. I don’t care if it’s Britney Spears.’ I became the backstage best friend. Whenever I showed up at a festival, the first thing I’d do is grab a bottle of whiskey and go knocking on doors to see who the funniest people are. You’d be surprised who the real f–king nutcases are."
I found that genuinely talented people are often inclined to that type of behaviour.
