Sorry for the late post today. Never heard of ca7 before and he's only uploaded one song before which is a mashup. It's a good mashup full of excellent vocals and Skrillex sounds. The result is a good time for your ears! The cat avatar reminds me of deadmau5. Maybe it is deadmau5 in disguise? Disguise or not, the ca7 definitely takes inspiration from deadmau5.
Also it is a free download!
