The day after Halloween will see the release of a 10th anniversary edition of Slipknot's sophomore effort, 'Iowa,' and despite being a decade old, that album may point the way forward for the masked metal mavens.

In an interview with Kerrang!, percussionist Shawn Crahan confirmed that the band plans to make another record, the NME reports. Although no timeframe has been set, it seems the music will hark back to an earlier sound.

"No one will push it, because it's going to be a big one," Crahan says. "It'll be closer to 'Iowa,' but it'll be sadder and crazier. And really thought provoking, it could even be conceptual."

That the Des Moines-born octet would return with a "sadder" album makes sense, given that it would mark the group's first collection since the death last year of bassist Paul Gray. As for "crazier," well, it is Slipknot we're talking about.

"We're still taking some time to reflect on our brother [Gray]," Crahan said. "Everybody needs to be collecting thoughts so they can get it out and no one has really had time to collect thoughts yet. But we're the f---ing 'Knot. And when we come out, you'll know your band is done."
