From the start this sounds way more classical than it does techno. The pace does pick up after a minute, but it's still a bit odd having a regular piano play the main melody in a techno track. I like the build-up though, but it feels a bit much at around 2:10, almost as if it clips. Scratches are awesome though; the beat is fast-paced and catchy. Can't think of anything to improve really, maybe start the build-up earlier? Keep it going!
Please contact me if you would like to use this in a project. We can discuss the details.
