Dunaj were a Czech alternative art rock band from Brno active between 1986 and 1998. The band is notable for its inclusion of Czech rock figureheads Iva Bittová and Pavel Fajt, as well as its own international success and influence on the Czech alternative rock scene. The band's name translates in English to "Danube", referring to the river of this name.
The alternative rock band Dunaj sis not release any new albums after 1998.
Based on the text Dunaj is an alternative rock band active between 1986 and 1998, which means that they didn't have any activity after 1998, therefore they did not release any new albums after 1998. I think the system got confused because of "albums" being mentioned in the statement, since there is no information about any albums in the text.
