|GonGoss is a composer who is famous for nursery-rhyme-style songs more than pop songs. He is one of the early Miku users, and his first work and the masterpiece "White Letter", which was released on September 9, 2007, recorded over 200,000 counts on Niconico.
His early music videos were uploaded with just some cuts of simple illustrations on them, and many of the videos were unnoticed. It was partly due to fan-made PV videos that GonGoss' songs became popular, including White Letter and "Smiley^2" ("Smiley × Smiley"). Later this composer collaborated with illustrators and uploaded PV style songs.
He is also known as Urakaidou-P (裏街道P Backstreet-P), which name he uses when he releases funny songs.
