Auringon talo (The House of the Sun) is a tragedia buffa, chamber opera in two acts for 10 singing roles, orchestra, synthetiser and strings. The opera tells about twin sisters Riina and Noora who abandoned the splendour of their upper-class St Petersburg home together with their family in the wake of the Russian revolution, and fled to Finland. The family made no attempt to adapt themselves and become isolated with tragic consequences. In the the old age the sisters escape from the sad greyness of their everyday life into the memories of their youth. This is the vocal score by the composer (with his original handwriting) with Finnish text.
