Canadian grindcore band Corrupt Leaders have a guest vocalist on a new track they’re recording. That in and of itself is no big deal. Everyone brings in a high profile guest for a song every now and then. However, this time, they used one of the band members’ 66  year-old mother. The clip shows the lady, who we’re only going to refer to as the band’s grindmother, laying down some screams, and doing a pretty good job at it. She seems to be having a good time too, and totally recognizes the novelty of appearing in her kid’s band. Move over Caninus and Hatebeak!
