Thirty Seconds To Mars are not just giving concerts - they're holding theme parties. 

The band will dress up for their concerts in different themes, and they encourage their fans to do so as well.

 They plan to have '80s Night, Zombies Night, Prom Night, Goth Night and Doctor/Patient/Medcical Night.

The band will announce the themes for each concert via their web site and Twitter.

Their tour kicks off tomorrow in San Jose, California.
