That sheet music isn't Apex Twin, it's a "joke" unplayable piece of written music called Faerie’s Aire and Death Waltz made by John Stump

I figured as much; I've never thought Aphex Twin's lines were particularly challenging, he's just got a very unique approach to sound design and composition.

Would you prefer a technically playable piece by way of Michael Angelo Batio?
