At least the one I best remember.. Absolutely Unique experience, a few dozens of people laying at the ground on the top of the St.Elias hill in the centre of Delphi ancient place (itself a unique place from many points of view) at 11 o'clock at night, only the stars above and total darkness and I.Xenakis in the console with 8 speakers put around the top of the hill towards the inside where we lay, sending random electronic sounds from all over!!!! what did you say??????
thanks!
