Siinamota’s Lost Album Therefore. Pre-sale and Release

Siinamota–also known as PowapowaP–was a well known and beloved Vocaloid music producer. He began making music in 2009, capturing the hearts of many with his electronic rock style. Hatsune Miku was featured in the majority of his music. Tracks and videos full of emotion and a vast range of genres were published by the young producer. Strobe Last, Sora no Sakana, and Palette ni wa Kimi ga Ippai are just a few of his many notable works.

On July 26, 2015, Siinamota’s management announced he had passed away at a young age of 20. That day, whole community grieved. Many sent their condolences to Siinamota’s family and loved ones. Even now, many of us still mourn the loss of Siinamota.
