I recently got realllyyy into classic tock ( i LOVE LOVE LOVE ALL kinds of music).. some of my fave classic rock is:

janis joplin
jefferson airplane
the doors
the lovin spoonful/john sebastian
KISS

and a shit load of others.. i'm sure my list will grow since i recently have gotten more into it and don't know a lot of pink floyd, zepellin, etc yet.. but i'm sure im gonna love all that too bc i can get into any kind of music pretty much
