It's An Arms Race,

no not the sort I first thought about,

you know what I mean, 'my gun is bigger than your gun','oh no it is not', 'oh yes it is', etc. it is an arms race to give a drummer a third or dare I say it a fourth arm,

but back to the original project Georgia Tech professor Gil Weinberg (left), created a robotic prosthesis for Jason Barnes, who lost his right arm two years ago, what's fascinating, though, is that the second stick allows Jason to do stuff that humans can't do, he can play faster, with a more stable beat, than any human can, because he's part robot,

moving on to a drummer with three arms, what is the advantage? more noise! if this is to be believed.
