Mick Jagger is probably the most interesting rockstar we have
If only for the sheer reason that he's been doing this longer and better than anyone we can think of. "Jagger has made it his business to understand and control the mechanics of his own stardom" reads in the NY Times article. Prestigious entertainment professionals have claimed that working with Jagger is to work with a true professional who understands every aspect of his field. This is not only true for the creative side of the business, but also the business and finance part of the operation. His oversight has made The Rolling Stones, the band he fronts, the richest in the rock history.
He's one of the first to recognise that bands are also brands.

"There was a window in the 120 years of the record business where performers made loads and loads of money out of records,” Jagger says. “But it was a very small window — say, 15 years between 1975 and 1990.” Touring is now the most lucrative part of the band’s business.
The Rolling Stones have three entries on the Top 10 highest grossing tours of all time. Since record sales began declining, artists have started touring more frequently. The result of this is that many of the highest grossing tours of all time come after 2005. The Rolling Stones' three entries though go all the way back to 1994.
So what the music industry is coming around to now, The Rolling Stones has pre-empted and actively worked on for over two decades. They are also ahead of the curve in terms of getting corporate sponsorships, selling song rights, and selling merchandise. These are now recognised as critical avenues for musicians to diversify their income.
