Since I don't agree with the 1 star-rating at all, I would like to warmly recommend this DVD. It's true, there is no film accompanying neither "Polytope de Cluny" nor "Hibiki Hana Ma". However, I very much love the short piece "Neg-Ale", that comes with the film "Vasarely". It's only 8 minutes long, but the music is very rewarding. I'd love to listen to other short pieces Xenakis composed for commercials: one for the German toothpaste "Odol", one for the Dutch aftershave "Pitrell" etc. I have looked around the net to find these, but so far no luck. Hopefully the great mode records is going to dig them up and present them. Thumbs up!
