Just been going through you tube and found this band, i don't know if it has anything to do with genre but they have seemed to mix 2 of the worst genres together. Screamo/crunk. i personally think it is complete rubbish but lots of younger kids seem to love it.
Link to awful mixed genre music
But also found some music videos that mix different genres that are actually very good
Hardcore Punk and Grime/hip hop
Artic monkeys and dizzie rascal
