https://en.wikipedia.org/wiki/Birgit_Nilsson_PrizeThe Birgit Nilsson Prize is the largest prize in classical music, awarded approximately every three years to an active artist or institution who has contributed an important chapter to music history. Towards the end of her unparalleled, long and distinguished career, the legendary Swedish dramatic soprano Birgit Nilsson established the Birgit Nilsson Foundation exclusively to support this Prize.
