Sergey Nikolaevich Starostin (Russian: Сергей Николаевич Старостин; born 1 January 1956 in Moscow) is a Russian folk and jazz composer and performer, famous for his modern interpretations of archaic Russian (as well as Lapps and Tuva) folk music. In his compositions, he sings, plays folk flutes (kalyuka overtone flute, svirel, pyzhatka), reed instruments (clarinet, zhaleyka, berben) and gusli.
In his early childhood, Starostin started to sing in a boys choir led by Vadim Sudakov. He started to play clarinet in school, and later graduated from Merzlyakov college of music, and then from the Moscow Conservatory. After graduation, he abandoned academic music for a while, completely switching to traditional folk instruments, tunes and non-tempered scales. By mid-90s, however, he started to collaborate with jazz musicians Mikhail Alperin and Arkady Shilkloper, forming a Moscow Art Trio group, and mixing together jazz and ethnic (Russian and Balkan) music. In his ethno-jazz compositions Starostin avoids harmonizations, staying within certain scales rather than sticking to chord patterns, which makes jazz played this way more "compatible" with traditional folk music. As of year 2011, however, Starostin is gradually moving from jazz and rock compositions back to more authentic folk traditional performance.
