As for visualisers, a lot of DJs use visualisers while performing live. A music
genre like psychedelic trance, for example, is best enjoyed along with some
intense visuals.
There can be two ways to show the visuals:
1. Projected on a screen with pre-programmed/programmable (maybe an interface
to easily develop newer visualisers too) according to analysed parameters like
BPM, frequency changes, and other information obtained from the track metadata.
2. Showing patterns using those big moving lights (I’m not sure what they are
called) that they use in concerts and parties.
From what I know, music artists and disk jockeys outsource visualisation tasks
to other people who handle and specialise in art/computer art. Why not provide
them with a way to make their own visualisations?
