Deep Purple have posted another snippet of music from their forthcoming album.

Right now, the project goes simply by a question mark and exclamation point, which singer Ian Gillan says, "Will become clear — as mud — later on. That's all I'm allowed to say. The question mark and the exclamation mark might get you intrigued."

Produced by Bob Ezrin, Deep Purple's 19th studio effort will be out on April 30th.
