We’ve been singing the praises of Andy Rehfeldt for years now. A talented guitarist, he’s been making heavy songs light and light songs heavy since before becoming a YouTube celebrity was something that was monetizable. And while he’s taken on Ozzy, Slipknot and The Sound of Music in the past, he recently took on Metallica’s “Master of Puppets,” and it could be his best work ever. First of all, he’s great at what he does, but it’s the whole eight-minute plus version, and it doesn’t get old or tired. As Metal Injection says, it’s really a testament to how great the original song is thirty-two years later. Andy is on PayPal, since he says he doesn’t get much from YouTube, and, well, this is certainly worth it.
