The Blue Man Group
Is there anyone familiar with this music, either live (phenominal), blu-ray, dvd full 5 channel music or CD?
It's a most unusual audio-visual experience, as they are totaly unique and most entertaining.
Their recordings are beautifully mastered and easily qualify as a "what makes your system sound good" - try "The Complex" in 5.1.
If you haven't heard their music, it's certainly worth investigation.
