In 1997, Jonas Trinkunas has received the national J. Basanavičius award for the fostering of traditional Lithuanian culture. During the Soviet period, he was one of the main participants of the Ramuva cultural movement, as well as one of the founders of the Vilnius University Ramuva folk culture movement. He is the author and editor of the book "Of Gods and Holidays, The Baltic heritage", Vilnius, 1999.

He has experience of directing various folk ensembles - the Žiūrai village ensemble (which has recently celebrated its 30th anniversary), the Sadauja ensemble, the Vilnius Institute of Art ensemble, and others. The sound of young voices saturates Kūlgrinda.
