in seperate rooms maybe they could compliment each other quite well. back to back though, personally, i would find very off-putting. i would'nt stick around for that at all! personally i dont enjoy dancing (and rarely listening) to breaks. it would frustrate me no end going from one to the other etc. id be interested to know what this 'techno' dj played. my opinion is that this combo would only work for those who liked both genres or ppl who are there just to party and care less about whats playing.
if your into it though then cool, cant knock you for having a great time.
