Just my thoughs exactly I wouldn't say (at all) that I play any really out of this world stuff or amazing skills.. but this is somethin I feel very strongly about ... techno is really diverse so I think u can serve up a really good melange... sure u have 2 b carefull and keep the plot, but it is really great seing ppl like :D cause they don't know were u r taking them next (mind u while keeping 2 the 4/4 techno :) ) .... seriously try getting some wacky booty vocals over a hardtechno tune and see people going crazy!! eheheh
I played not so long ago with a "very famous" dj/ producer (Italian name ending in ola) and although he had very good skills I totally bored me out.. 30 m and I called it a night.. in fact I think that if he had worst skills would b better 'cause it would sound like such a continuos bongo/ conga loop :) ..
