Kornelije Kovač (1.1.1942 - 13.09.2020)

Famous Serbian composer, pianist, keyboard player, producer and arranger. His career as a professional musician started in 1961 when he formed his first jazz trio 'BKB'. In 1967 he joined 'Indexi', but stayed with them for a short time. After leaving them he formed famous 'Korni Grupa' band.

And so on it goes, with fusion, progressive music, some vocal tracks, some instrumental, a brilliant lost record really, lovely to find, and many thanks again for bringing this to our attention!
