Mariusz Duda just shattered a quarter-century of prog rock legacy. The Riverside founding bassist and frontman announced yesterday he’s leaving after 25 years, citing toxic band tensions and a suffocating fake image. Now he’s shifting everything to his solo project, Lunatic Soul, which will become his primary creative outlet.
🔥 Quick Facts
- Announcement date: April 23, 2026, via official Facebook statement
- Departure reason: Internal toxicity blocking creative music production
- Band status: Riverside effectively over, unlikely to continue without him
- New focus: Lunatic Soul to become live band and main project
A Bold Final Statement After 25 Years
Duda‘s departure marks the end of an era for the Polish progressive metal band. In his statement, he expressed deep gratitude for 25 years of achievements and fan loyalty. However, he made clear this wasn’t an easy decision but rather a necessary one for his mental health and creative survival.
“I am proud of everything this band has achieved,” Duda explained. “But most of all, I am proud of the incredible and extraordinarily loyal fans.” Yet beneath the gratitude lay frustration, acknowledging that maintaining a false public image had worn him down.

The Toxic Environment He Couldn’t Ignore
Duda didn’t mince words about what broke him. The band’s internal situation no longer permitted him to create new music, his primary life passion. He described being “tired of pretending and forcing a smiling band image which, in recent years, has had nothing to do with reality.”
His recent Lunatic Soul double-album “The World Under Unsun” revealed the full scope of his pain. The track “The New End” was specifically written as a farewell to Riverside fans, capturing emotions he found difficult to control. The music video accompanies his confession perfectly.
What This Means for Riverside
| Detail | Status |
| Founding member departure | Mariusz Duda (vocalist, bassist) |
| Remaining members | Piotr Kozieradzki (drums), Michał Łapaj (keyboards), Maciej Meller (guitar) |
| Band continuation likelihood | Extremely unlikely with new lineup per Duda |
| Last lineup era | 2001 to April 2026 |
Duda made his position crystal clear: “I do not see any possibility of the band continuing in its current line-up. And restarting it with a different one would be extremely complicated.” This statement suggests Riverside may have effectively ended with his departure, marking a historic moment for progressive rock.
“I am tired of pretending and forcing a smiling band image which, in recent years, has had nothing to do with reality. I can understand the sadness and disappointment, but I see nothing wrong with putting your own needs first at a certain point in life.”

Lunatic Soul Becomes His Primary Project
Lunatic Soul, his solo project since 2002, will now get the full force of Duda‘s creative energy. The band will “soon enter a new phase and become my main studio and live project.” Already boasting eight studio albums including the ambitious double-album “The World Under Unsun” released in 2025, Lunatic Soul offers him complete creative freedom.
This transition gives Duda exactly what Riverside couldn’t provide, a space where he controls every element. He remains on good terms with most band members, but creative incompatibility made continued collaboration impossible for him.
Is This the End of Prog Rock’s Elite Polish Band?
Riverside never issued a response to Duda‘s statement, leaving the status of the band entirely ambiguous. With the primary songwriter, vocalist, and eldest founding member gone, can the remaining three musicians continue his legacy? The answer remains uncertain, but Duda‘s firm stance suggests the iconic lineup may be finished forever.
Fans face an unexpected farewell. For 25 years, Riverside delivered complex, emotional prog metal that defined the genre. Now that chapter closes, and only Lunatic Soul continues the Duda sound fans cherish. Will he achieve greater success as a solo artist freed from internal conflict?
