I don't know about the Athens show, but I attended the Thessaloniki gig and the mosh pit therein got out of hand several times, I haven't seen such passionate audience in ages.
To commemorate Mark Reale (R.I.P.), the band had his guitar case on stage and people shouted his name constantly.
As for Riot V, they are in perfect shape, they played stuff from their hard rock period (WHICH SLAYS!!) and songs from Thundersteel, Privilege of Power and Immortal Soul.
