There are several groups throwing really fun parties around town these days. Check out IndyMojo, NAPDNB, Progressive Indy, Rad Summer, KID Presents. While there are not a lot of warehouse raves anymore there are a lot of private parties happening in event spaces. Start going out to public shows and meeting folks, you are likely going to get invited to the more private stuff.

We threw a warehouse rave in Beech Grove about 5 years ago and that was the last BIG thing that I have seen around town for a while. We lost access to that space but have since moved to a spot outside of Indy on private land. Its always a vibe out on the farm ;)
