Rumoured to have been discovered by Aphex Twin sleeping on a park bench in Tokyo, Raczynski first appeared on the scene in 1999 with 3 albums in that year alone. He went on to explore hallucinatory, bassbin-rattling IDM, outsider junglism and traditional Polish folk music amongst other paths, collaborated with Björk, produced a soundtrack for a PlayStation game, and remixed the likes of Autechre, Jonsi, and CLIPPING. In 2019, Disciples began looking after his Rephlex era catalogue, putting together the Rave 'Till You Cry compilation of unreleased gold from the vaults, and reissuing his classic Samurai Math Beats LP. His last studio album, ADDLE, came out on Planet Mu in 2022. "Bogdan was a massive inspiration for some of my tracks on the Drukqs album, the fact he was doing it all on shit PC tracker… totally amazing. This was before 99.9 percent of people used the computer for everything. His records are so underrated." - Aphex Twin
