This 2004 mix accreted itself around the Greek folk song “To Whom Can I Tell My Pains”, which I discovered while randomly surfing through the iTunes Music Store, and which reduced me to tears on the first listen. As a setting for it I pulled together other songs with the right levels of sadness, distance, exoticness or thrilling dissonance.
This also gave me a chance to attempt something I'd wanted to do for a while: add "serious" 20th-century classical music to a mix. This ended up as the most varied mix I've ever done: it also has folk music from several cultures, rock, electronics, and unclassifiable experimentation. I hope it works for you.
