Dunaj, a Czech alternative rock band from Brno, was formed in the 1980s. Initially known as Kolektiv, they changed their name to Dunaj in 1989 and released their debut album Iva Bittová + Dunaj. The group included vocalists Iva Bittová and Jiří Kolšovský, guitarists Josef Ostřanský and Pavel Richter, bassist Vladimír Václavek, and drummer Pavel Fajt. In 1991, they released their second album, Rosol, which was critically acclaimed for its avant-prog rock anthems. The band disbanded in 1998, and Kolšovský died of cardiac arrest shortly afterwards. Dunaj resumed its activities as a trio in 2019, consisting of Václavek, Ostřanský, and Koudelka. They released albums, including the album Za Vodou (2022) and Mňau (2025) with Jana Vébrová.
