Upright bassist Kaisa Mäensivu, 33, was on her way to a gig when she came across a herd of cows happily grazing in a field.
Kaisa was accompanied by saxophonist Max Zenger, 35, and her husband and drummer Joe Peri, 32.
The trio had been on their way to a sound check at the Aland Sea Jazz Festival in Aland, Finland but decided to play a concert for the cattle.
