Not since the late 80's or early 90's has there been a decent complex guitar solo in a popular song.

this isn't true but the problem is that the solo is nolonger mainstream. the few guitar bands that are mainstream make it very hard for solo-players to make it. as many have said, the solo isn't dead, it is just hiding from ridicule. personaly i can't wait for the solo to reture to the world, as proud and powerfull as it always was, but i think we cound be in for a long wait
