This is definitely one of the best album ever made. Each track has got his own soul, but is perfectly crafted to fit to the album's sound.
It's impossible for me to find "the best track", because it's an LP to be listened from A1 to D2.
In this album you can easily find deep house, minimal, tech house, techno, all mixed togheter in the unique "SCSI-9 sound".
Personally this is one of the "10 albums I'll take to a desert island"
