@mars90000000,
there's some good stufff out there. there's a whole steampunk belly dance sub-genre, Abney Park is popular with them.
Nothing real new musically, you can listen to some music from the early 1900's and think it is steampunk. Which I guess is part of the appeal.
Costuming is big, but not a lot of purists which is somewhat disappointing. People mix everything from about 1850 to 1920 and think it works together. It doesn't. Just looks mish-mashy.
