The Pirkanmaa prog rock giant and the pride of Kangasala, Tabula Rasa, perform their song “Omantunnon rukous” live in the studio of the programme Pop-Liisa hosted by Vesa-Matti Loiri. The band was one of the most important groups of the second generation of Finnish progressive rock and a central influencer in the early years of Manserock. Remembered as the band’s guitarist and composer, Heikki Silvennoinen later became famous as a comedian.
