Caught wind of this on Facebook tonight. Sound Remedy has described this as his darkest remix yet. If you were to ask me, I'd probably agree.
I imagine that a number of remixers have tried turning Beethoven's imminently recognizable "Moonlight Sonata" into a slow, haunting electronica track. But I don't expect that many of them accomplished so very successfully. Okay, maybe it's not that frequent (my searches are coming up empty). Either way, this is a pretty well-done remix of a classic, classical song.
