Does anyone know who the masked figure in the ushanka and trench coat was? Perplexed both me and my dad. I didn't watch much footage of the last couple live concerts so I have no idea if this was a normal thing or if it was a one-off. Regardless, this mystery player KILLED it! Buckethead himself was also playing bass during this. Best jam session I've ever heard.
