We as humans tire of the same ol same old, and are looking for something new. It has become practically exponential with the population increase. The more we have, the more we want. Check out Best Buy's collection of C.D.'s/artists once. That says it all.
It used to be that you could name them all: Beatles, Rolling Stones, Cream, The Who, Led Zeppelin, The Beach Boys, Dave Clark Five, Jefferson Airplane, Mamas and the Pappas, The 1910 Fruitgum Company, Tommy James and the Shondells, The Turtles, The Animals, The Doors, The Byrds, Lovin Spoonfull...there were lots then, as we had FM (sort of considered underground music that the druggies listened to) and AM bubblegum music (that the teeny-boppers listened to). But there was a finite limit of these groups.
Today, there are a gazillion groups. All these guys started to learn after watching acts like Kiss and Alice Cooper and Ozzy Osbourne, that the wilder their shtik, the better their chances. They started off by having mid-length hair. Then they added smashing guitars. Then they started painting up their faces. Then they started eating bats. Then the fireworks started going off. Then, they all grew long hair. Then, they punked out with black-death themes, rings, tattoos...till we got to today: Marilyn Manson. And I think even HE is a has-been now. Just like that. I can see through that guy. He aint' really wacked like he comes across. He does that just so he can con kids into thinking he is some heavy messed-up dude. He don't fool me.
Anyway...you ever hear some of the old bands (lead singer) sing? Ouch. Stick a fork in them. I can't getr into watching a bunch of 50-60 year olds trying to act like they are cool, while you see their wrinkly, gravity stricken faces...listening to their howling. Every once in a while I see someone who is as excellent as they always were. Willy Nelson, at 70, is one of them. Paul Rogers from Bad Company still has a good voice. There are others. But some are pathetic and need to hang it up. Creedence Clearwater Rival is faking out people and they are really Creedence Clearwater Revisited, now. There is only one band member I think that is the original guy. Look at all the ones that died in plane crashes, od's, and suicides. It is a phenomenal number.
O.K., this is driving me nuts. I'm in a room with two other 50 year olds. None of us can remember the name of the group that sang "Inagodadavida". And I HAVE that album! Duh! (I'm posting this from a friends house)
