I have posted (in both the Belarusian and Polish sections) up some piano music and songs by the Belarusian/Polish composer Yan Tarasevich (also spelt Jan Tarasiewicz). The below is google-translated from his Belarusian-language Wikipedia page:
Yan Tarasevich (Polish: Jan Tarasiewicz; September 23, 1893, Sokolka now Podlasie, Poland - June 18, 1961..) - Polish and Belarusian composer, pianist and teacher.
He received his musical education in St. Petersburg. He participated in the creation of the Belarusian People's Republic. He worked in the Belarusian school in Grodno. Then he lived mainly in Sakolshchyne.
He wrote music for piano, choral and desktop, as well as songs. Inspired by Belarusian folklore. He left behind 113 compositions and one unfinished concerto.
In 2013, in Bialystok took place Yan Tarasevich Festival, dedicated to the music of the Grand Duchy of Lithuania.https://be.wikipedia.org/wiki/Ян_Тарасевіч
