Back in the 80's I was in a band with a hippy chick lead singer. She turned me onto all sorts of cool stuff, music and otherwise. But she said that everything had been done when it came to music, and I disagreed. And still do. But I understood her point.
Someone posted a band that I'd never heard, and I checked it out. But all I heard was a re-hashed, classic rock type song. Even the video was a lame throw back.
Overall, and this is just my personal belief, but I think lots of bands are just purposely trying different things. And I'm not talking about taking a few different styles and influences the songwriter may have, and just blending them, because that's simply what inspires him/her. I'm talking about just doing weird s**t in the hopes that something will stick to the wall. I really believe that's what's happening in a lot of music these days.
And you know, on the one hand, this may be exactly what Bohemian Rhapsody sounded like to some people. So one person's "trying weird-ass s**t" may be another's "musical masterpiece." Who's to say? But I still wouldn't crack eggshells into a sauce, trying to come up with some new flavor.
