The fact that Mairo Nawaz is playing at Appelsap for the fourth consecutive year should tell you something. No longer the rookie of the capital’s club scene (with residencies at Jimmy Woo, Bitterzoet, Paradiso and De School, as well as Rotterdam’s Bar), the flamboyant Amsterdam DJ and Patta Soundsystem member is now a 21-year-old tastemaker on an international level, playing everything from the latest Atlanta rap music to obscure soul and disco songs, whatever fits the mood of the moment.
