Every gig has got the festival audience dancing so enthusiastically at the Keskipohjanmaa arena that the crowd has had to be organised.
On Friday night, the start of the Night Trill was delayed because some of the dancers had to be diverted to the grassy fields around the grandstand to dance. But that didn't matter; that's how legendary Kaustinen Night Theatre is!
The dance floor of the arena can hold around 300 people at a time. In addition, there is seating for around 1600 people.
The Wentus Blues Band also had the crowd dancing in the early evening on Friday. Next up, Samuli Edelmann will fill the Arena at 20:00.
The night-time trill will get festival-goers practising their steps during the day and then dancing late into the night. (Photographer: Krista Järvelä)
