Of course, most of the rock stars exploited their image - they might have been "rebels" when they started out, but everything gets recycled. Which is why so many of them seemed to follow a template, career wise.
I do believe however that, in spite of the image, rock stars has, well, a "star" quality. This doesn't mean that the image wasn't made up, quite the contrary - indeed they projected a larger than life
image.
I remember reading an interview with I can't remember which producer who was speaking about those kids asking him about the legendary artists he'd produced and all the wild tales - punch bowls filled with cocaine on the mixing board and groupies in the vocal booth, people smoking, etc.
Nowadays, you walk into a studio, you're more likely to see a bunch of guys texting their girlfriend or looking for gluten free bread in the cantine... At the end of the day, that's not what legends are made of.
Rockers grew up and became reasonable. It's okay. But it's quite uninspiring.
I'm always reminded of this picture, taken during the recording of Ace Frehley's solo album. Now that
IS rock and roll.
