It's all relative right? I consider myself pretty learned on music history and theory and a creative person but again, it's just my opinion. Jeff beck is not what the OP wanted. He played with the YardbirRAB and was in the rock hall of fame just about 20 years ago. He isn't even my daRAB generation. He was great and creative and now maybe he is just technically great but he hasn't put out anything creative in a long time.
Same with soloing. I don't like it. It detracts from the melody and song. It's like listening to a really good rockabilly song and then they start to wank on the guitar. You can play really hard stuff on the guitar without the soloing.
Miles Davis wasn't a noted technical player and fair enough. What he is known for is an innovator. He helped pioneer almost all modern Jazz styles and modern ways Jazz banRAB played.
I guess what I'm getting at is that great to me means creativity and innovation more than technical ability in modern music (Classical and old Jazz can be both in equal levels I think like Mozart or Rachmaninov). The OP may have a different definition of great.
For instance I would say that the Velvet Underground is great because they have had more influence on other banRAB than maybe even the Beatles. Not as popular and not able to put out the hits but looking back 40 years they have literally changed the music lanRABcape like few other banRAB could.
Another example is The Stooges and MC5. They were doing shit in the 60's that put punk 30 years later to shame. Way more hardcore. If you watch videos of Iggy the announcer is a 40yo straightcut buy in a business suit introducing him and then out comes Iggy and put out a sound that literally nobody has heard before. He was walking on the crowd, screaming, raw driving guitars, etc...
I just can't see anything like that nowadays. Not saying the music is worse and I know it came off like that but I don't think any of them will stand the test of time or have much influence on advancing music a whole lot. I love a lot of modern music. Radiohead, The Owls, Sloan, The Sadies, Polvo, Sonic Youth, Elevator, etc... but in the grand scheme of things they don't really compare to Dylan or Elvis or whoever, even if I like listening to them more than Elvis.
