Nujabes will forever be one of my all time favorites.
Nujabes worked with Shing02 on the "Luv(sic)" tacks. They made parts 1-3 together, but after Seba's death many doubted that the series could ever be completed. However, parts 4 and 5 had already been completed, and were released shortly after Nujabes' death. Although part 6 was not among the previously completed tracks, it was released on February 26, 2013, 3 years after the day Seba had died. According to Shing02's official Facebook page, the instrumental to what would eventually be part 6 was discovered on Nujabes' cell phone a few weeks after his death.
