Georgios Kachrimanis (tenor and alto Trombone) was born in Athens on the 26th of December, 1977.
The trombone came into his life at the age of 15, although he had started playing music at the age of ten in his local fanfare band. Shortly thereafter he started playing in the Athens Student orchestra. The first time he played music professionally was at the age of 17, with the Radio Symphony Orchestra of Greece. In 2002 he won his current position as principal trombone of the Athens Philharmonia and in 2003 finished his studies with a 10 and first prize. During the next 10 years Georgios won other auditions and played with all the major and minor orchestras in Greece, appearing as a soloist on a number of occasions. Since he was a child he wanted to discover the source of classical music. After years of the same mediocre musical life in Greece, the lack of creativity did not seem any more to maintain the glamour in his life. So the moment came when he decided to make his childhood dream come true. He attended the Royal Conservatoire of The Hague and in 2015 graduated with a Masters Degree.
