Irena Santor

She's noted for singing in clear mezzo-soprano, considered one of Poland's biggest icons and is referred to as an influence for younger singers.

From 1951 to 1959 Irena Santor (then Wiśniewska) was a member and the main soloist of the Polish folk group Mazowsze, with whom she toured all continents.

Her father, Bernard Wiśniewski, was murdered by the German Selbstschutz in the autumn of 1939, a few weeks after the start of World War II.

Górzyński was impressed with her vocal and recommended her to Tadeusz Sygietyński, who was creator and manager of the folk group Mazowsze.

He organised casting and accepted Irena's candidacy but stipulated that she will take singing lessons under the direction of opera singer Wanda Wermińska.

Her mother died that same year, so Irena moved to the Karolin, where she graduated music school and passed the matura exam.

Starting with the 4th edition of the event in 2025 the official name will be: Irena Santor "Vistula Sounds" International Festival[3][4][5].
