Boris Lenko was born in 1965 in Ružomberok (Slovakia). He studied accordion with Anton Pittner at the Conservatory in Žilina and with Marta Szökeová at the Academy of Music and Drama. White still a student, he scored successes at several competitions, including the Grand Prix at the International Competition in Andrezieux, France (1987) and Second Prize, awards of the Slovak and Czech Music Funds and an honourable mention in duo playing (with Lubomír Žovic) at the Competition in Hořovice (1986).
Since 1990, he has developed a fine career, performing a broad repertoire comprising both transcriptions of early and classical music and works written specially for the accordion. Thanks to his successful appearances at contemporary music festivals ('Melos-Ethos' and Evenings of New Music in Bratislava), many composers have written pieces specially for him. Slovak music occupies an important place in his repertoire.
Foreign tours have taken him to Germany, Austria, Slovenia, Switzerland, Russia, Ukraine, Yugoslavia and France. Since 1992, he has also appeared in a duo with accordionist Raimund Kákoni. He has collaborated with various ensembles ('Požoň sentimentál', veni, 'Vapori del Cuore', Slovak Sinfonietta, the Slovak Chamber Orchestra). Last year he founded his own ensemble alea (piano, violin, double-bass, accordion), whose primary goal is to perform works by Astor Piazzolla.
Since 1989, Lenko has been a professor at the Academy of Music and Drama in Bratislava. He also gives master classes. In 1999 he taught during the Akkordeon Woche in Biel, Switzerland
