I never replied to you. Sorry about that.
I actually agree with you, but I think I didn't express myself properly. Generally, I much prefer older music--Rush, Iron Maiden, Black Sabbath, Dio, Rainbow, Savatage, Kansas, Fish-era Marillion, Gabriel-era Genesis, The Eagles, King Crimson, and The Moody Blues for example. That said, I'm inclined to disagree when people say there's no good music anymore. For example, I'm not as much of a fan of punk as I was in my teenage years, but the band that's stayed with me is Flogging Molly; their lyrics are meaningful and their music is well-composed. Power Metal came of age in the 90's, and while a lot of people don't like it, it's kind of hard to argue against the quality of Nightwish or Rhapsody of Fire's music, for example. Their grand orchestral compositions (backed by a real orchestra!) have left a mark on the musical landscape (if you have time, check out Ghost Love Score for an example, though a couple of my subsequent links are more vital to my point, so you can skip this one). In the prog world, The Flower Kings offer majestic, beautiful melodies that blend everything from jazz to classical eastern influences.
My two favorite bands are "new." Dream Theater got its start in the 80's, but it's really a 90's and 00's band, as that's when it came of age. They were influenced by the classic prog bands of the 70's (Genesis, Yes, etc.), hard rock (Rush), and metal (Iron Maiden, Metallica). Give Learning to Live a listen; yes, it's from the early 90's, but I think we both count that as "recent," and to be honest they're still writing masterpieces now even if they're not as poetic as they used to be. This song is filled with feeling, with real beauty, and the lyrics are well-composed. As I understand it, it's about AIDS, but it's ambiguous enough that it can be applied to life at large.
Exhibit B: Spock's Beard, my other favorite band. This is an interesting one--they're playful and don't take themselves as seriously as Dream Theater. Their lyrics are questionable sometimes. But their music speaks for itself, and sounds just as good as any of the 70's and 80's bands I named. Consider The Doorway; hell if I know what it's about, but it's one of the best songs I've ever heard. There's a warmth to this song that's also completely unique and hard to find in rock in general, but even harder to find in modern rock. Now, these bands aren't from the 70's or 80's, but IMO their output is better than a lot of classic bands. They showcase energy, innovation, and a real passion for the music itself. So while trends have gotten arguably worse, there are good bands if you dig enough, and sometimes, you don't have to dig much at all (Dream Theater is quite popular).
Sorry for the long post, but I'm enjoying this conversation and I like recommending bands to people/ getting recommendations. Truth be told, I'm not a huge fan of the bands you brought up; they don't reach me emotionally, and that's my rubric, silly as it may sound. I do respect Pink Floyd and Led Zeppelin quite a bit, and I definitely like The Beatles and The Who. Never heard of The Kinks, though. What are they? Also, what type of music do you play?
