I started djing 6 years ago with 2 cdj 100s and an old stanton mixer. It went from psychedelic music to electronic to minimal and finally landed on the boarder of minimal and techno. I chose a track selection of an average of 128 BPM for the 30 minute set. It's a nice bpm to work with, but the harder the better so playing live i would gladly raise it.
Enjoy my thirty minutes!
