To honor and celebrate Record Store Day, Nuclear Blast and TESTAMENT will release a limited-edition (1000 copies) seven-inch picture disc containing two bonus songs the band recorded during the sessions for their latest album, "Dark Roots Of Earth". Side A is a cover of the SCORPIONS song "Animal Magnetism", while side B is TESTAMENT's take on IRON MAIDEN's "Powerslave". Both covers can also be found on the deluxe edition of "Dark Roots Of Earth".The "Animal Magnetism" / "Powerslave" picture disc will be released on April 20. In a 2012 interview with Metal Assault, TESTAMENT guitarist Eric Peterson stated about the band's versions of "Animal Magnetism" and "Powerslave": "I picked 'Animal Magnetism' [for us to cover]. For 'Animal Magnetism', we tuned it down to B. It's super low, and we slowed it down. It's already a slow, hypnotic song, but we slowed it down a little bit more. That's where the song just sucks you in. It puts you in a trance, which is what I think the SCORPIONS meant to do with the title 'Animal Magnetism'. It's kind of like a hypnotic beat through the whole song. But ours is, like, hypnotic to death or something. It's got a real drone-like sound to it." He continued: "The 'Powerslave' song, that's a song you really can't change [laughs], because it's pretty modern and pretty up to date, and it's pretty awesome. But it really fitted in with the rest of the record, and I think what we really do to it is definitely give it justice. It sounds very close to the MAIDEN version, but it's just got that extra tightness and crunchiness to it. And the way Chuck's [Billy, TESTAMENT vocalist] singing it, it really puts a good vibe on it. He doesn't sound like Bruce [Dickinson, IRON MAIDEN singer] at all. He really just sounds like himself." Record Store Day celebrates the culture of independent record stores by playing host to in-store events/performances, signings and special product releases on a global scale.
