You’d have to be a little bit psycho and just a tad socially awkward to think that Slipknot’s “Psychosocial” was begging for a banjo cover. But, as he has in the past, Rob Scallon ventures where no other musician will, and he makes it work, in this case with a band of masked musical vigilantes (and Leo Moracchioli!) to help him out. Not quite the same masks as Slipknot, but they get the job done.
