On the album Emotions, Štěpánka Balcarová set to music eight basic human emotions described by the American psychologist Robert Plutchik: joy, trust, fear, surprise, sadness, resistance, anger, expectation. She recorded a concept album with the repertoire, which had a concert premiere in August 2022, with the Czech-Polish quartet, whose members are Nikola Kołodziejczyk (piano), Jaromír Honzák (double bass) and Grzegorz Masłowski (drums).
