how great thou art song All non-believers, who don't believe "rock and roll" is dead, should check out today's music charts. Whether its Billboard or Rolling Stone or America's Top 40, the top of the charts are ruled by such artists as Rihanna, Lil' Wayne, Kelly Clarkson, Bruno Mars, and LMFAO, not merely one rock artist inside the bunch. One issue you have to give thought to the clientele you might be serving along with the form of songs being played no matter if by DJ or live bands. If your theme fluctuates, you have to be sure that your nightclub lighting system can fluctuate with it in color and intensity. That means if someone night you rock your home out and the next night roll with some golden oldies or country and next night it is just a disco diva night, you need your nightclub lighting design to reflect ambience in the songs and clientele.
