It seemingly has become impossible for these has-beens to fade away since the money they make touring is so astronomical. According to Rolling Stone it has quadrupled in the last decade and 85-90% of it goes to the performers as opposed to 15-20% for CDs. Here are the richest rock stars in 2005 according to Rolling Stone. Not the prevalence of the geezer rockers.
1. U2 - 139 million
2. Rolling Stones - 92.5 mil - short tour
3. Eagles - 63.2 mil
4. Paul McCartney - 56 mil
5. Elton John - 48.9 mil
6. Neil Diamond - 44.7 mil
7. Jimmy Buffet - 44 mil
8. Rod Stewart (oh, come on!) - 40.3 mil
9. Dave Mathews - ?
10. Celine Dion - ?
There were only a few rap artists in the top 20 or 40 richest.
Secondly, music is becoming more democratic over time - the cost of entry into the market has fallen dramatically, and the money to be made is likely to become more "diffuse" as well.
To conclude, the era of the big rock star is coming to a close. We can be thankful for this.
