yea, i mean, every dj has to keep changing their sound in order to still be in demand. that's what all the big djs in the world do. once carl cox and sven vath spun techno, then hard techno, now carl does some house and minimal and sven does some electro and minimal also. you gotta keep moving with the times. playing piano house tracks from early 90s everytime can get extremely boring at times.
