i dont think there's such a thing "the big trend", however i must say that since nirvana's "smells like rock dying" the trend is to make the music as simple as possible, and im not talking about the music as whole but about lead guitar only... you just dont have players like SRV, Page , blackmore, etc any more. the only two types of rock players we have today is travis's lead kind which got nothing to do with lead guitar at all and the metal type, who are often have great technical abilites, but lacks any feeling and emotion in their music
i really hope that one day there'll be a SRV kind of music trend, so people like me will be able to watch MTV all day long
