Speedy J Breaks Down Generative Workflow Behind Epic Experimental Track 'JT33Unstable Core'

Speedy J - aka Rotterdam native Jochem Paap - first broke through as part of wave of artists associated with Warp Records' early 1990s Artificial Intelligence series, alongside likes of Autechre, Aphex Twin and Richie Hawtin. After decade of influential releases, he stepped away from releasing full-length albums in early 2000s, instead focusing on standalone tracks, collaborations and his improvisational Stoor project. This month, however, Speedy J has returned with his first album in more than 20 years - Walkman - 20-track collection of boundary-pushing compositions designed to explore nature of what an electronic album should be in 2026. Ahead of release, we visited Paap in his Rotterdam Stoor studio to discuss creation of album's most ambitious statement, epic 15-minute 'JT33Unstable Core'.
