There's always a push/pull between consolidation and creativity. It's just economics that the music on the radio, as defined by the media giants like Clear Channel, is either the creative original stuff - Hendrix, ZZ Top, U2 etc., or the consolidators like the Black Crowes, Coldplay, Cheryl Crow... of course you can hear the influences of Hendrix, the Beatles and all, but they put things together that had never been mixed that way before. Buddy Guy could do a stellar job on "Red House", but he sure never wrote "Night Bird Flying" or "The Wind Cries Mary."
Sell 'em what they bought before. This has also got to be true in putting the bands together that are hoping to make serious money - if you auditioned for a metal band, surely they'd want to hear "your sweep thing" and "your tapping thing." The scouts that feed bands to the machine always claim to be looking for the next big ORIGINAL thing, but whenever they find a potentially Big Thing that's creative, they're too weird for the record companies! Which is one of the many, many reasons the big companies are dinosaurs just waiting for their comet. And you have a zillion guitarists like Guthrie Govan, who can ride anything with fur but doesn't really seem to know what to DO with it. And great guitarists like Joe Bonamassa, still singing about freight trains and bad women what done him wrong*, because if he wrote songs about flat tires and hotel bedbugs they'd be even dumber than what he's doing now! :toothy12:
*(If you made a list of the greatest rock bands who made their bones with songs about bad women what done 'em wrong, you'd surely get the Allman Brothers, Led Zeppelin and the Eagles right at the top. And if you made a list of the greatest rock bands who banged more groupies in a totally throwaway style, at the top of the list you'd get, ummm... the Allman Brothers, Zepp and the Eagles. Don Henley was reputed to fall in love just so he could break up, just so he had something to write songs about!)
