Welcome, Lisa. Some great choices there, many/most of which I'm into myself. We have a subforum for classic rock (runs off the "Rock and metal" one) so that might be a good place for you to start, but wherever you go I'm sure you'll be welcome and find something that interests you.
I'm sure Exoskeletal will be along shortly to advise you of something you need to do in order to join: listen to him carefully, he's a wise man.
Once again, welcome!
