Philadelphia-bred indie folk favorites Sadurn have officially broken their silence, announcing their highly anticipated sophomore album, The Underworld. Set for release on 16 October 2026 via Run For Cover Records, the project marks the band’s first major collection since their acclaimed 2022 debut, Radiator. To celebrate the announcement, the group has shared the album’s stunning lead single, ‘whole thing’, alongside an evocative new music video.
Expanding the band’s graceful blend of alt-country, bedroom pop, and intimate indie rock, The Underworld leans even deeper into songwriter G DeGroot’s heartrendingly personal lyricism. The lead single, ‘whole thing’, serves as a brilliant testament to this sonic evolution. It is a sprawling, beautifully paced cut of warm vocal hooks, weeping pedal steel, and lilting drums that builds to a rich emotional climax, practically begging the listener to hit repeat the moment the final note fades.

The road to this second record, however, was anything but straightforward. Following the sudden, unexpected success of Radiator, DeGroot found themselves blindsided by the compounding pressures of industry expectation, a painful breakup, and sudden physical fallout.
“I was having chronic pain, problems with my voice, gut issues,” DeGroot reveals. “It felt so urgent to try and keep things going, but my body was saying no.”
The crisis reached a breaking point when, following an initial recording session in the Poconos in early 2024 and a brief attempt at touring, DeGroot completely lost their ability to sing—a silence that lasted for eight gruelling months. In a bid to heal, the songwriter made the radical choice to leave Philadelphia, put the overdue album down, and live on the road for a year via various work exchanges.
It was within that year of transient stillness and intimate living-room solo shows that DeGroot’s voice began to return, bringing a profound sense of clarity with it. Returning to Philly to finish the tracking alongside bandmates Jon Cox, Amelia Swain, and Tabitha Ahnert, the band enlisted Mark Watters (Alex G, Hop Along) to mix the final product.
The resulting 9-track record serves as a metaphysical dedication to coming back to oneself. From the unvarnished spontaneity of ‘why does my heart’ to the methodical, eight-minute closing masterpiece ‘only angels’, the album balances lush band dynamics with raw emotional catharsis.
“The underworld is the hard times, but it’s also about getting back,” says DeGroot of the album’s core philosophy. “You go into the underworld so you can find clarity about your own being and come back changed. That’s just my fundamental belief about healing; it’s not about wallowing, but you do need to move towards the darkness in order to transform it and get unstuck.”
