well, regarding a gig, during RR2005, maybe because its in the heartlands where people work, go market, go home relax shake leg, so hence they did not bother about the gig.
If RR2005 was held say, outside ngee ann city, or outside heeren's, i believe the crowd response would be greatly different. So location plays a huge part i guess. We also need publicity. If say the gig collaborated with mediacorp, it will be well publicised and hence increase the no. of people watch.
in short what i want to say is, gigs must have good location and publicity besides having bands to participate and equipment in order to be a very very successful one.
