I'm not talking about music that you dislike, for that see the corresponding Nickelback Bitches!!!!! thread (sorry, junesquad

As I mentioned in the Is there a Insert Thread Name Here thread, Aphex Twin does it for me a lot. Icct Hedral particularly, although "Curtains" also has a spine tingling quality to it, quite unsettling. There's also a Turkish electronica band called Ventochild that makes me reach for my teddy bear when I hear them.
...but that's just me.
