Thanks! I am going to start at the top and work my way down. I have listened to some Mars Volta and I like some of their songs, The Widow comes to mind. I will give them another listen. I found them around the same time as I discovered Coheed and Cambria, another band that has some good tunes. I agree with Queens of the Stoneage.
I do like Jazz, but am kind of particular. Kenny Burrell is one I can listen to all day.
