MUSIC...Music...music ~~~~ I've had repetitive beat syndrome for over 25 years now & have been heavily involved in the dance, rave & club scene and culture since the early 90's. 
Starting off as a (natural born)raver then DJ ( n0mad ), label rep ( Noom/Gstar )before going on  to being an  'event facilitator'  working & networking with various contacts, soundsystems & clubs all over the place - specialising in various house, trance & techno electronic music genres  mainly in South Africa, Japan, Russia, Holland & France etc but especially in London, Germany & Ibiza . 
Over this period I, like many,  have seen dance and club culture change, evolve and progress all over the world, all due to digitization, evolving laws, the drugs & attitudes of the party people & rave culture as a whole. 
Having retired from the 'front line' party side of things last year, well 'mainly' ;) as I was hoping to at least hit the big 50 and still have 6 years to go haha
