The Bester Quartet is the new incarnation of Jarosław Bester's Cracow Klezmer Band, a quartet of violin, bayan (Russian accordion), percussion, and double bass, who perform a wholly unique kind of improvised Jewish folk music. Under the latter name they have released six albums on John Zorn's Tzadik label: three records of original material, two of interpretations of Zorn's material, and one live album. These albums are among my favorites of the new millennium. The Bester Quartet is essentially the same group, but with a new double-bassist: Mikolaj Pospieszalski. This new album, again on Zorn's label as part of the "Radical Jewish Culture" series, offers more of the group’s exciting explorations of Jewish music via highly energetic, but also mournful, folk-like song forms.
