Just when I thought nothing would ever beat my experience with the heavy metal of the 80s, I stumbled upon this (these), that is, Lemmy and Metallica playing Damage Case and Too Late, Too Late in 2009 (rehearsing it first, and then in concert). Of course, this comes from those freakin’ 80s (ok, end of 70s) too.
Here you can watch the end result (in concert) too.
