I was once invited to a birthday party as a guest, and due to a muck-up by the DJ whose laptop decided it was time for a software upgrade and basically told Serato to “go f*ck yourself”, I ended up DJ’ing that party from my iPhone using the djay app. It turned out to be some of the most fun I’ve had in DJing a house party in years, especially when a bunch of twenty-something yr old kids throw words like “awesome”, “hero” and “savour” at you. They seemed to like the music too! My point is, forget the gear, if you’re confident in your abilities, gear is (almost totally) irrelevant.
