I have to go with Christian artist Rich Mullins. He's from Indiana so I got to see him before he became 'big' - in fact, I met him backstage before an Amy Grant concert before I even knew who he was!! I lost track of how many times I saw him live and of course have all the albums. (And I can do the cup trick - anyone else know what that is?!) I was devastated at his death as his music played such a part in my spiritual growth during that time and will always be special to me.
