Styx is a great band! I saw them when Tommy Shaw first joined them.
I recently saw Rush, they were awesome. Also went to see Stray Cats, The Pretenders and ZZ Top. That was a cool concert. I had never seen The Pretenders or The Stray Cats.
I really like a lot of the 70's music also. A CD that I just got is Everything But The Girl, Accoustic. Some really good versions of songs. One of my favorite on that album is "Love is Strange".
