First off, well, what can I say?
This song is truly amazing. I don’t know what classifies as Techno, but this feels right.
The song starts slow, but that’s good imo. It allows a powerful build up, which you took advantage of and made a great climax. The instruments worl well, I couldn’t find any points where one instrument stood out too much.
The ending us great too, not much to say though.
All in all, a massive well done, and I wish you still made music here. Not to annoy you for it, though!
