Katarzyna Nosowska is the lead singer of the Polish rock band Hey. She is also known for her solo career, which in contrast to Hey's guitar-driven rock delves more into electronica. The author of Hey's lyrics, she is also a columnist in several Polish magazines. She recently recorded a solo album Basta, which according to the artist, is particularly important to her because it is a very personal one . Katarzyna Nosowska will perform compositions from that album during the concert in Opera Leśna.
