I looked up "hatzigiannis" and found a site for Mihalis Hatzigiannis. Below is his website (if that's who you were talking about). It shows in the discography section that his last CD was in 2004.
There is a cd called "Live" that is listed at Amazon [UK]with:
Original Release Date: May 24, 2007
and at cduniverse they have "Akatalili Skini" with a 'street date' of the same.[May 24th]
Possibly the same ones as referred to in the above post.
