Dimitri Papanikas

Greek name, born in Sardinia -Sardinian is an Italian dialect but quite different- and studying and living in Northern Italy (Bologna), and living in Madrid and Buenos Aires. His accent has a lot of foreign elements, but it's a very nice and idiosyncratic mescolanza.

Yes, I think his accent is nice too.
