The Announcement: End of a 25-Year Era
On 23 April 2026, Riverside frontman Mariusz Duda posted a social-media statement declaring that his “journey with Riverside is coming to an end” after a quarter-century with the Polish progressive-rock outfit. Duda said the band’s current internal situation prevents him from pursuing his primary passion—creating new music—and that maintaining a “smiling band image” no longer reflects reality. He added that, while he remains on good terms with most members, Riverside cannot continue with its existing lineup and a re-formation would be “extremely complicated.”
Background: Riverside’s Rise and Recent Turbulence
Riverside formed in Warsaw in 2001 and quickly became one of Poland’s most internationally celebrated prog-rock acts. Over 25 years the group released eight studio albums through InsideOut Music, including landmark records such as *Second Life Syndrome*, *Rapid Eye Movement*, and *Wasteland*. The band suffered a major blow in 2016 when founding guitarist Piotr Grudzinski died unexpectedly, after which Riverside continued as a four-piece. Duda’s 2025 solo project Lunatic Soul, *The World Under Unsun*, was later revealed to contain a coded farewell to Riverside.

Official Statements & Responses
