First starting in 1993, Radio 1's essential mix hit number 500 last night which was recorded live from Liverpool. The 500th act was Airplane from Belgium (Myspace). Pete Tong and Sasha also stood up, plus this man; Richie Hawtin.
If you're unaware of Richie Hawtin check out his soundcloud. Hawtin is known for producing and DJing minimal techno and he also produces under the alias of Plastikman, as well as various others. You can listen to him on the Essential Mix via the Radio 1 website for the next 7 days.
