As pointed out by my bandmate in Fognozzle and Girls of Slender Means (and former partner in Wow Cool), Mr. Pete Von Petrin, the brilliant piano renditions transcribed and performed by Vika Yermolyeva have had too much play in viral reblogs from elsewhere towards certain works and maybe not enough attention to the artist and her work directly. Her version of Master of Puppets is a classic… in whatever sense of that word you need to reference; but, there are many other gems of arrangement and performance you should check out on her YouTube page, including versions of well known songs by Massive Attack, Radiohead, The Stooges, Radiohead, Portishead and many more… to varying effect..
