To day june 14. 2009 Ib Kai Olsen celebrates his ninety years birthday. br Ib Kai Olsen (IKO), born june 1919 in Copenhagen, is one of the pioneers of danish traditional jazz. After WW2 he joined the then newly established Hot Club of Denmark, among whose members a club band - the first danish trad band - was formed around 1948, mainly inspired from the early british jazz clubs. br br As could be expected the beginning was rather mediocre, so Ib felt he could do better than that and bought himself a cornet. After having practised for some time he joined Hot Club Jazz Band and started playing 1. cornet. Later on it separated itself from the now fading Hot Club and became Ib K. Olsen's Jazz Band. 90 years and stil goin strong. Happy birthday Ib. br The people on the music is br Co. Ib K olsen, second co. Palle Nielsen, Cl. Bent Tranberg, Trb. Arne Hojberg, Pno.
