Abney Park is a steampunk-themed band who models themselves as the crew of the airship Ophelia. If you scroll down the above link you'll see several photos of their guitarist/fiddler wearing a kilt. I don't know if he wears the kilt all the time (in his normal life or in his persona), but I noticed that. And I looked up the web page after seeing their photo (with the kilt) in the Boston Phoenix (print version).
