I am working as VJ for a Danish Downbeat/Electronica artist, called Rumpistol.
I am always working to make a very exact match from music to visual perception. That means i pre-record a short "music video" for each specific track on the setlist, in exact mood and coherence with it. Mostly abstract visual variations on each theme. And then "cut it up" live, in correlation with the artist playing live. That gives to me a very neat coherence, with the live music, only supporting the atmosphere of the music, without stealing attention.
If you have a bright monitor, here is some pictures (from the audience) from one of the first gigs at "Vega" in Copenhagen:

Here is some snaps from GRID, from each "track" in a newer setlist...
