Based on a lecture held in May 1999 at the Betsalel Arts Academy in Jerusalem, Israel.
Some hundred years ago, specialised musicians were busy keeping up the pace with the frantically flickering images on big screens in movie theaters. An opposite trend that has existed for more than twenty years, is now gaining momentum: Visual artists are reversing the process. They illustrate the music and thus create an experience similar to silent movies. They accompany the music that dictates the rhythm. When no apparent action takes place on stage, some additional (visual) activity has to be offered to an audience that cannot be satisfied with patiently sitting on its seats. In the night clubs, the spoiled and satiated club­bers do expect an extra kick. Whether it is the decoration which is active or only parts of it - it is important that the pace of the sea activities is related to or synchronised with the actual rhythm of the music it accompanies. Active involvement in the production of live visual ima­gering during concerts or active visual reactions to musical activities is a basic need.
Technically simple and easily available methods are necessary to satisfy these needs. The electronic image - in the form of video (since the end of the Seventies) - followed by com­puter technology (at the end of the Eighties) seem to be the right means. Today, sophisti­cated tools are at our disposal; instruments that allow automated and direct responses to the music, and powerful projectors producing brilliant and clear images. The visual artist can focus on the essential: choosing the elements, while the machines take care of the right rhythm. The projections can be integrated into the traditional light show without competing with it.
Vjays operate similar to live broadcast directors, mixing one source with another in wipes or fades, using single or multiple mixing boards. The work of the VJay can also be compa­red to the work of the DJay. There is a basic difference, though: Because, when using either common video tapes or state of the art computer technology, they can not go to a visuals store and check out new releases. Any VJay has to create his own material and archives, very often their own special tools and gadgets.
