Surrender started Hypnagogia with a powerful emphasis. Dubstep and drum and bass permeate the album, and the mixing quality is noticeably improved relative to previous albums. Trance and bass, an unrecognized sub-genre that has been adopted into modern liquid drum and bass, is ingrained throughout all of Memex, and Hypnagogia expands upon that, particularly with both Lucidity and Catharsis. The cover is an image of Lain from Serial Experiments Lain, tied with electrical cords and laying on the floor. The illegible words are from a Buddhist sutra, and the entire image has been converted into binary code. The album was released in September 2016.
