The story goes a little like this: At some point this year, stickers featuring the Berlin producer Rhywtwo’s face grafted onto a Pokemon character began to show up in major urban centers around Europe and beyond. Who created these strange stickers? And what do they mean? Both questions remain a mystery, but what is not a mystery here is that the producer, in the spirit of good-natured collaboration of a sort, has made a track that responds to the stickers—a scorching dubstep tune that can be enjoyed by all, no sticker required.
