I think maybe one of the big downfalls for current music was overuse of voice processing. Maybe not, who knows.
For a long time, I was that guy. Hendrix, Black Sabbath, Led Zeppelin, etc. That was it, everything else was crap. But I am really expanding these days and enjoying all kinds of music. I hope to spend some time on the newer music and see if I can find some I like. For example - dubstep, some of that is really awesome stuff, love it. But some of it is kind of so-so. There is a lot of rap I like, but I lot I don't like as well. I think there are gems buried everywhere.
Right now I am mining backwards and backwards. All the way to the 20s. I just think its a riot to listen to those old blues songs, it makes you realize those guys way back then were the ones who came up with the stuff that become everything in rock, country etc. I'm not sure if anyone from the 60s onward has come up with a blues/rock single guitar lick that those guys didn't play first.
I have worked my way through the 30s, 40s and 50s. There is lots of great stuff buried in there. Heck I even am listening to some country/western music. If you were to tell that to myself 40 years ago I would have called you crazy. For example, Move it On Over, Hank Williams SR, 1947. Good lord, the guitar work in there, just awesome. In 1947! There is great music in every decade I think. But, also there can be stuff that is not so great in there. Heck even my most favoritest bands often have crap. There's some new stuff by Metallica that's...not good. And then there is "Van Hager". BLECH. But these are all opinions of one person. Others have their own taste. I think its all good, listen to what you want, and try to branch out if you get bored. Its so great you can find this music on the interwebs these days, and Vid I always like your music threads to help me expand. Keep them going!
