I love all the music that has branched off just from the existence of Dance Gavin Dance. It's pretty awesome if you think about it.
I definitely have been introduced to a ton of great music due through DGD that I might have not gotten around to checking out had I not listened to DGD first and also seen them live.
A Lot Like Birds
Hail The Sun
Tides Of Man
All of them solid "dgd-related" acts. Not to mention that Kurt Travis, Tilian Pearson, Jonny Craig, and Matt Geise all got things coming up solo-wise.
