What can I get my fiance for his birthday?

He said I don't really have to get him anything, but I want to get him something special. He'll be turning 35. He loves music and he plays guitar. Mostly Metal, and he just got a new guitar. He already has all of Metallica's CDs. He also loves the Chicago bears and Carolina Tar Heels. Mainly Carolina. I love him with all my heart and I really want to surprise him, so can you please help me decide on the perfect gift? .
