I suppose that Phil, Geddy, and Ian could do some sweet backing vocals. This is more like my weirdo, stick 'em in a room and see what crazy shit they come up with band. More prog than metal, I guess. But I'd like to see the non-metal guys stretch it a bit. Mike would definitely have to introduce them to the devil.
