Yesterday there was a double-bill, with first the Hong Kong Welsh Male Voice Choir singing - the first time they have performed in Wales after being formed 40 years ago by ex-pats of Welsh origin in the former British colony.
They were followed by the Linkoping University Male Voice Choir who showed off their broad repertoire from classical choral music to new works and what they describe as "high-spirited escapades".
The Hong Kong choristers left their Swedish counterparts with the perfect link by belting out their version of Abba's Take a Chance on Me.
The concerts continue today (Friday) with appearances by guitarist Achille Jones and the Coro Serpeddi choir from Sinnai in Italy (pictured below).
Out on Centenary Square yesterday there was another packed programme of free entertainment which included an Indian bhangra dance troupe and dancers from Indonesia.
Up on the field an attraction in the Ampitheatre just before lunchtime was a spirited performance by the choir from Ysgol Maes Hyfryd Specialist School in Flint.
