Joé, the DJ behind the Pulsar series chose to change DJ/Producer name to Crystal Eardrum with the release of his first Electro-House single, ''Crisp'', which you can hear in Pulsar Vol.9 or here: http://soundcloud.com/mdam-music/crystal-eardrum-crisp. Joé wanted a producer name more meaningful to him and his music passion than his first name. He chose Crystal Eardrum because to him it means something hard yet pure you can perceive through your Eardrum.
