Sadie Dupuis, the guitarist and vocalist behind indie rock outfit Speedy Ortiz, will release a new Sad13 mixtape called 1331 in the coming weeks. The project marks her first solo music under the Sad13 moniker since 2020's Haunted Painting. The mixtape consists of thirteen tracks, each running approximately one minute in length, a deliberate constraint that shapes the project's aesthetic and scope.
What sets 1331 apart is its complete DIY execution. Dupuis wrote, performed, and engineered the entire mixtape solo. This represents her first time handling recording duties independently in fifteen years, a significant shift in her creative process. She serves as the sole performer across all thirteen songs, stripping away the collaborative arrangements that typically define her work with Speedy Ortiz.
Three tracks from the mixtape are already available, offering an initial glimpse into Dupuis's stripped-down approach. The compressed format invites comparison to projects like Vince Staples' Whack World, another recent work that embraced the mini-song structure to explore ideas within tight compositional boundaries.
The 1331 title carries numerical significance that mirrors the project's structure. This kind of conceptual precision reflects Dupuis's broader artistic sensibility. As a principal songwriter for Speedy Ortiz and a prolific solo artist, she has consistently demonstrated interest in formal constraint and experimental approaches to song construction.
The mixtape arrives during a period of sustained activity from Dupuis across multiple creative outlets. Her work continues to signal the broader indie rock world's embrace of shorter, more experimental formats. By stepping behind the engineering console herself, Dupuis takes complete ownership of the sonic texture and production choices that typically involve collaboration. The result promises to offer fans a uniquely intimate perspective on her compositional voice.
