Um.... I had a quick browse of this thread and noted a lot of electronic fans and stuff... which is cool.
I was kinda wondering if you meant a good song good song, or one that sounds good and makes the most of Empeg visuals?
I'm probably biased, because I am the *ultimate* Tool freak, but have you tried "Eulogy"? Its on the album "Aenema".... actually a lot of songs on that album are good for visuals.
Try it and see what you think - it looks fantastic at least.
If you've never heard Tool, or are not into Guitar driven stuff, then give them a chance. I find a lot of electronic and dance freaks are easy to get into Tool becuse the rythmns and arrangement are so good.
Anyway, if you *do* try them, give them a chance - they take a bit to get used to if you're not used to it. Well, some people seem to anyway.
Aenema is the best to sample, then try the latest one - Lateralus.
Let me know what you think
