When do you sing? Is it when you feel good?... Kalin Veliov and Maria Avramidi ‎Kalin Veliov & Maria Avramidi sing even when they don't feel good. ‎

This is how their song "When I Sing" begins. But this is not their first joint ‎title. The two artists have been brought together by the music project "AMAZONIA" - the Brazilian Latin dance group of which Kalin Veliov is the producer. Apart from the Greek presence of Maria, the international line-up of AMAZONIA is complemented by Latin music artists from Brazil, Argentina, Angola and Nigeria.‎

Another popular musician is featured in "When I Sing" – in the recording of the song and inthe shooting of the video we can also see bass player Boris Taslev, known mainly from the Bulgarian jazz scene, currently also part of the Folk Music Orchestra of the Bulgarian National Radio. All other musical instruments in "When I Sing" were recorded by Kalin Velov, who is the author of the music, text and arrangement of the song.‎

A percussionist, drummer, singer, songwriter and producer, Kalin made his first stage appearance when he was 10 years old as the drummer of the children's band "Pim-Pam" conducted by Boris Karadimchev. After graduating from the Lyubomir Pipkov National Music School and the National Music Academy  in Sofia, his love for Latin music took him to the Conservatory in Rotterdam, the Netherlands, where he studied Latin music with world-famous names.
