Noboru↑-P (のぼる↑P, 江藤昇 Etou Noboru) is a senior producer who is influenced by Linkin Park, Bon Jovi and other rock music creators. He composes music of seemingly-contradicting genre, rock and ballade. His initial composition is death metal, his work, however, is somehow completed as the genre mentioned above. Both have a high reputation in Nico Nico Douga. On June 14, 2015, Noboru↑-P announced on his Twitter that he is retiring from making music and thanked for the support everyone always gave him. Two years after his announced retirement, on September 2017, he released a new song, and has returned as a VOCALOID producer since then.
