Quantic

I discovered Quantic 4 or 5 years ago, when my musical taste first started shifting into down-tempo / trip-hop / lounge / esoteric electronica / whatever you want to call it. One of my all-time favorite musicians, Bonobo has been compared to Quantic, so it's no wonder I was attracted to him.
