This is a video of the internet’s resident acapella group Rockapella MayTree performing Metallica’s ‘Master Of Puppets’ as a tribute to Stranger Things’ Eddie Munson. It is a must watch — that mouth guitar solo is WILD. A whole lot of tongue and funny faces going on. Like foreplay, but also nothing like foreplay except for the tongue and funny faces. Well, okay, and all the strange sounds and hell bats.
