My favourite DJ would probably have to be Deadman. I've never seen him live unfortunately, but I have always wanted to. Theres many others, but im hopeless when it comes to remembering them off the top of my head. I love most genres of electronic fro. Glitch hop to Psytrance, DnB, all the way through to house, it just depends on the mood. Right now a couple of bangers im loving are; Hey you by Dope lemon, remixed by Cedric Gervais, and Mink & Shoes (dub mix) by Psychemagic.
I remember seeing seeing Infected Mushroom play at a bush doof Here near Cairns, just after a tropical cyclone had passed. The rain was fucking terential and the whole crowd was just stomping in the mud! You were constantly being splashed in the face by mud puddles, but you would just wipe it off and carry on.
Another epic concert i went to was in a football stadium in a place called Santa Cruz in Bolivia, where i watched David Guetta play. Im not a massive fan, but the show itself was awesome. They had these guys in robot costumes, on stilts, that could shoot a massive stream of sparks from each hand. They were always moving in sync, and the backdrop was a giant screen with constantly changing visual effects. It really was an awesome show! The cppious amounts of cheap cacaine might have helped......
I also saw a brazilian DJ called Gui Barrato play in this epic nightclub in Buenos Aires. It was a stunning old bank with marble stairs leading up to the front door, followed by a marble clad entry hall with epic chandeliers etc. There were a few separate bars and a night club inside the old bank vault. It was nuts.
