Not wishing to be too pedantic, but then what else is sample spotting but a pedant's game?
<piece of classical music?> Carmen Burana by Karl Orff. This is used in the Old Spice adverts. Also used on 'O Fortuna' by Apothesis.
That's "Carmina Burana" by Carl Orff. And it's the whole symphony that is called "Carmina Burana", while the first (and last) "song" (all the pieces were based on Latin poetry found in a monastery) is the most famous piece and is called "O Fortuna". It was probably first made famous to the masses in the movie "Excalibur". Hence F.C.B. (Remixed by Nick Skitz) had a dance track called "Excalibur" (and also "Excalibur 2000", when they failed to come up with a new idea a few years later.) Apotheosis (both spellings appear on the net) had their dance remix back in 1992, as you mentioned. Enigma also used samples from "O Fortuna" heavily on the "Behind The Mirror" album, and I can recall 'The Art of Noise' used it too. In fact, I would hazard a guess that it may be the most commonly sampled piece of "classical" music (Orff lived from 1895-1982) ever. If anybody else knows of other examples where significant use of the track has been made then I'd actually be interested to know about it since I've sorted started a collection of them. Michael
