Nedyalko Nedyalkov was born in 1970 in the town of Haskovo into a long line of folk musicians. Even as a young child, his interest in music was apparent. At the age of four, he made his first attempts to play the accordion. At seven, he started going to the music school in his hometown. Later he continued his musical education on the kaval, a traditional Bulgarian folk instrument and applied to the prestigious School for Musical Folklore in Shiroka Luka. While a student there (1984-1989), he developed his skills and abilities on kaval and was recognized as one of the most promising young musicians of his generation. In 1989, he graduated with honors from the Music School in Shiroka Luka and was immediately accepted to study at the Music Academy in Plovdiv. He received his diploma in 1993. During his student years, he performed as a soloist in the academy's folk concert orchestra, as well as with many other groups. Nedyalko won several first prizes at the National Competition for Young Performers in Pleven in 1986, 1988 and 1990, as well as the special prize for the best young performer at the highly competitive contest in Stambolovo in September 1990. From 1994-1996, he was a soloist in the Pazardzhik Folklore Ensemble and the Shoppe Ensemble in Elin Pelin. In 1996, he won a competition and was hired as a soloist in the Orchestra for Folk Music at Bulgarian National Radio, where he still plays today with a wide range of talented fellow musicians.

Besides having an excellent grasp of traditional kaval styles and techniques, Nedyalko also possesses one quality that is rarely found in other Bulgarian musicians, demonstrating his unique talent - namely, his mastery of the quarter-tone system, which is exceedingly difficult to apply to kaval. He performs all manner of Balkan and ethnic music with ease and is able to masterfully imitate on kaval most instruments in the flute family from around the world. His style is marked by brilliant virtuosity, free and flexible improvisation, in which he expertly interweaves with much feeling and finesse different, often difficult types of playing. His music carries us away to an imaginary space without stylistic or genre limitations, pointing us towards a future without borders.

He was personally invited by Jordi Savall, a prominent contemporary musician, conductor, and ambassador for intercultural dialogue around the world, to take part in a major new project by Maestro Savall and Montserrat Figueras entitled "La tragédie Cathare", which concerns the history of the Bogomilism. This encounter laid the foundations for joint creative work and cooperation that continues to this day and has resulted in numerous concerts and new projects, including “Mare Mostrum”, ”La Sublime Porte”, “Balkan Spirit", Bal*Kan-“Cycles of Life” and “Dinastía Borja”, which was awarded a Grammy in 2011 for Best Small Ensemble Performance.
