System Of A Down bassist Shavo Odadjian has said he is up for a System Of A Down reunion, however he says it’s not up to him.“Trust me, I’d love to get on stage right now,” he wrote on his Twitter. “It’s not only up to me man. Lets let things happen organically.”Earlier this week System Of A Down frontman Serj Tankian quashed rumours of a reunion saying: "We call it an indefinite hiatus and that's how we still look at it. Nothing's changed. We always have offers to play but we haven't decided to do anything yet."
