A women’s choir located in Republic of Czech that sings exclusively Hebrew music. The choir started as part of a Hebrew class at Ostrava University by Dr. Tomáa
Novotný. Later it grew into a performance group. The Adash website has samples of music and discography. Two of their CDs are devoted to Hebrew songs, but they sing liturgical pieces and Yiddish and Russian lanugage songs on their other two CDs which include many solos for folk music as well as choral work. The CDs are Adash & Barbora Baranová, Jewish Songs II, Jewish Songs, , and Hebrew through Songs. The site also includes videos through YouTube.
