I want a show when I see alive pa. I want to see the dj/producer not just the top of there head stuck in there equipment I want to see them feeding of the crowd and using that to fuel and direct the set.
I think that you need a blend of all 3 aspects of the tunes that your playing
1.tunes that every1 loves and knows as if they was playing them at home
2.remixing tunes throw the live pa, effects loops ect ect so that there is still that familiarity but you get that wow factor when you introduce something new that excites the dance floor
3. new unheard tunes/sounds always pushing the boundaries forwards you can ever go wrong with that
(but more of 2 and 3 imo )
