There's no shame at any age in asking your mum for a little bit of help - even if that "help" includes them screaming for your grindcore band.
Corrupt Leaders frontman Rain Forest got a very special guest in to help record some vocals for a new record - his 66 year-old mum (presumably not called "Mrs. Forest").
And she goes HARD. AS. F. Mum's screamo-growling combo sounds perfect on top of the furious double kick-pedal track that Rain lays underneath.
The apple truly doesn't fall far from the tree. And this apple's got a hardCORE (sorry).
