NTS Session 4

NTS Session 4 is the fourth and final installment of Autechre's NTS Sessions 1–4, originally broadcast on NTS Radio in April 2018. While the project as a whole is a sprawling exploration of the duo's North-based generative software patches, Session 4 is distinct for its pivot toward long-form ambient and drone. It represents a significant departure from the rhythmic complexity of their mid-career work, leaning instead into the 'slow-burn' philosophy seen in tracks like 'Perlence subrange 6-36'. The album is anchored by 'all end', a 58-minute piece that has been cited by critics as one of the most significant ambient works of the 21st century. The recording context is purely digital, utilizing Max/MSP to create sounds that feel both alien and strangely physical. It was released to universal acclaim, with critics noting its ability to make digital processes feel emotionally resonant and spiritually vast.
