I would have to say Tesla is the best example of this. While not necessarily a true hairband, their music is fresh and original but also sounds like them. They always stayed true to their sound which is more than I can say for many bands.

Also I heard a song from 2009 from Danger Danger that sounded amazing! It's called "Hearts On The Highway"... here is the link. http://www.youtube.com/watch?v=2QD8iPLwErs

Obviously my favorite band in the world Bon Jovi is still making great music and selling out stadiums all over the world!

What do you guys think?
