The Cracow Klezmer Band was a Polish jazz quartet formed by accordionist and composer Jarosław Bester in 1997 in the city of Kraków, and recorded for Tzadik Records. The group performed at Jewish Culture festivals in Hungary, Finland, Poland, Prague, and the Czech Republic. Its sound was different from what most people would consider to be traditional klezmer music - instead of danceable versions of traditional Yiddish songs, and free-form fantasies, and laments, The Cracow Klezmer Band played often dark and brooding but soulful and dynamic original virtuoso compositions instead in the klezmer form. Some songs could be considered dance pieces, but there were none of the traditional Bulgars, Freylekhs or Horas.
They also imitated non-musical sounds using their instruments, for example the sound of a creaking ship or a distant crying bird; this actually has a long tradition in klezmer music.
In January 2007, the band changed its name to the Bester Quartet, with the same line-up.
