I think Caress of Steel was the first Rush I heard. A mate was badgering me to listen to this "ace band" and he brought CoS and Hemispheres around to my house. So Bastille Day was the first song for me. I admit it sounded a mess on first listen and I left the albums for a while, before eventually giving them a try again. I fell in love with Rush then. I loved and still love Caress of Steel and it's definitely in my top 5.
