Here is how you find out if it sounds like Aphex. Play it for a hardcore Aphex fan that isn't into message board speculation and could give a fuck less about researching artist. Also, not knowing of Steinvord is pretty important. Play some of his very Aphexish tracks and say "Hey this is the new shit from Aphex, what do you think". Analyze response. I for one thought Aphex the second I heard it a couple of years back on Myspace. Unless someone comes out and strait up says it, we can never know who the hell it really is.
