J.S. Bach - Passacaglia & Fugue in C minor, BWV 582 (Synthesized) 

And finally: the Passacaglia and Fugue in one go.
I have revised the two parts, added some reverb here and there, slowed down a little the Fugue, and here we are.
If you want to check out the two parts individually (the videos use a different visualisation that might help a little more to follow the melodic lines), here they are:
