We’re all for alternative versions and covers here at Moshville Towers. We’re especially for them when the cover artist makes the song “their own”, really putting a stamp on it and changing it appreciably from the original.
Well, you certainly can’t beat this as an example of that. Vika Yermolyeva, also known as “vkgoeswild”, absolutely shreds (or the piano equivalent) the Metallica classic. This is only one sample of her work. Have a dig round her YouTube channel for songs by loads of other acts from Carcass to Porcupine Tree.
