Generative AI spins out infinite versions of the new documentary, “Eno,” in theaters. (Photo: Gary Hustwit) Whether you know Brian Eno’s name or not, you’ve likely heard his music. He’s worked with countless influential musicians, including Coldplay, David Bowie and U2. He is best known for creating the ambient music genre, and the new feature film “Eno” dives into his dynamic music-making process and workflow. The creative process behind the film is interesting, too. Director Gary Hustwit programmed AI to alter each theatrical screening, so no show is exactly the same. The film — or, at least, one version of it — premiered at the Sundance Film Festival and is now being shown worldwide. Catch it at 7 p.m. Thursday at the Varsity Cinema, which sells tickets online.
