What's some good rock music right now?

I've loved rock music my entire life. My dad got me into the classics like zeppelin, van halen, lynyrd skynyrd. Just raw rock and roll. I listened to stuff like POD, linkin park, disturbed through high school but when I got to college no one listened to any of this kind of music. Over the past two years I've gotten accustomed to listenin to more dance music because of school. I guess what I'm asking is what's some harder/heavier music? I can't stand listening to katie perry or pitbull 8 times a day on the radio anymore. Please help me out here.
