On a scale of 1-10: Supernova.
Sorry about the lame pun.
I'm fussy about techno. I'm a metalfag at heart, despite having a secondary love of punk rock, and I appreciate live music in general. Techno is much harder for me to get in to, so take this as a compliment when I say I loved this oh so much.
More objectively: There's actually a proper melody line in some places, which while not essential to good music, is never a bad thing. Ever. The drum track was well-written and well-synthed (everything else was well-synthed too, but as an ex-drummer, the drums stood out the most). There was a proper use of dynamics. It was well-structured. Everything about this is good.
So many techno artists could learn from this.
