I think Old school (I think Patsy cline shirt would be cooler than Patty Smith..)or kitch would be best as if you go for indie rock cred, people know you are and it might come off as trying too hard, esp, if you don't know everything about that band. Even Better, local obscure record shop T, or ones with cool image like a record or old microphone, etc...What do you think of home made or paid-to-print? Oh, and what's your take on hats with kitten ears because I'm a big fan, but is there a rule about those?
