According to Shing02's official Facebook page, the instrumental to what would eventually be part 6 was discovered on Seba's cell phone a few weeks after his death.
Part 6 was not among the previously completed tracks, but it was released on February 26, 2013, on the third anniversary of Seba's death. However, parts 4 and 5 had already been completed, which were released shortly after Seba's death. Seba collaborated with Shing02 on the critically acclaimed Luv(sic) hexalogy, making the parts 1-3 together, but after Seba died unexpectedly many doubted that the series could ever be completed. Seba was also a member of the production duo Urbanforest, an experimental collaboration with Nao T. Seba collaborated with Japanese artists like Uyama Hiroto, Shing02, L-Universe, and Minmi, and with various underground American hip hop acts such as CYNE, Cise Starr (as a solo apart from the hip-hop collective CYNE), Apani B, Five Deez, Substantial, CL Smooth, Fat Jon, Terry Callier as well as British rapper Funky DL. He is considered a pioneer of lo-fi hip hop, or "chillhop". Seba adopted the stage name Nujabes (his name spelled backwards) and became notable for his approach to producing hip hop beats, often blending jazz influences into his songs creating a mellow, nostalgic and atmospheric sound. In adulthood, Seba owned a record store in Shibuya, and also founded the independent record label Hydeout Productions. Seba was born on February 7, 1974, in the Nishi-Azabu district of Minato in central Tokyo, Japan. Seba's production techniques and career have also been compared favorably with J Dilla, who was born on the same day. Although relatively niche during his lifetime, Seba has since achieved posthumous acclaim and been referred as the "godfather" of lo-fi hip hop. In 2010, Seba died in a traffic collision at the age of 36.
Additionally, Seba collaborated on the soundtrack for Shinichirō Watanabe's anime series Samurai Champloo ( Music Record: Departure and Impression) in 2004. He was the founder of the independent label Hydeout Productions and released two collection compilations: Hydeout Productions 1st Collection (2003) and 2nd Collection (2007). Seba released two studio albums during his lifetime: Metaphorical Music (2003) and Modal Soul (2005), while the album Spiritual State was released posthumously in 2011. Jun Seba ( Japanese: 瀬葉 淳, Hepburn: Seba Jun, Febru– February 26, 2010), better known by his stage name Nujabes ( ヌジャベス, Nujabesu), was a Japanese record producer, audio engineer, DJ, composer and arranger best known for his atmospheric instrumental mixes sampling from hip hop, soul, and jazz, as well as incorporating elements of trip hop, breakbeat, downtempo, and ambient music.
