it's absolutely nuts live especially at bass-heavy shows. a lot of the smaller guys have really good stuff, but Excision's visuals are the andromeda/farbrausch tier of VJ production imo:
Just for point of reference, there are a handful of AAA motion graphics studios that put together visuals for these tours -- for instance, IMMANENT did Excision's current Nexus Tour visuals. Really amazing shit.
