Speaking to Kerrang! magazine last month, Slash revealed that Velvet Revolver were busy auditioning replacements for singer Scott Weiland who acrimoniously left the rock supergroup in 2008. And, if the auditions went well, VR would be hitting the studio to start work on the follow up to 2007's Libertad immediately."There're two guys we're trying out at the moment, so we'll see how that goes," Slash told K!. "You might not know one of them, the other one you definitely will!""I'm off the road until January, so if the stars line-up and we have something going on between now and January, we'll be writing then and there!" he added.Well, according to a post on Slash's Twitter, it looks like the guitarist is indeed in the studio. "So far so good in the studio!" wrote Slash. "Got a couple brand new riffs, pretty heavy stuff!"Does this mean they've found a replacement for Scott? Post your speculations below.
