Being a person who attempts to play the guitar and growing up when I did, I love the guitar instrumentalists: Vai, John 5, Satch, Dinner Music For The Gods, and Buckethead.
I'm also sure there's another hundred thousand I'm not familiar with whom I'd love if I had the chance to hear them.
It's well documented that I love instrumental guitar, but I also greatly enjoy the symphony, blues guitar, and even some jazz.
Vocals and lyrics aren't the basis of a song for me, so I can appreciate the gorgeousness of simply hearing someone playing an instrument. Having said all that, I know that most people in the United States cannot appreciate instrumental music and require vocals or it's not a song.
I just don't get that.
