Took me a while to realise the artwork is moving. Or am I still high? It's nice, it shows how much a different tuning can affect a song. Anyway, original still far better. I like E flat too.
This is an unrealeased song called "when the hills ran red" or something like that but is known as "unrealeased kill em all song." Ron mcgoveny talked about it in an interview you can find on youtube. It was probably Mustaine's riff because later it became Sleepwalker by Megadeth.
