kz is a popular electronic-genre Vocaloid producer known for his work with Miku, most notably "Tell Your World". He has used the name RE:NDZ for his non-Vocaloid work and his "P name" is ダイソンP (Daison-P), from the misheard phrase "Light Song" in the song of the same name.

It was then resold to Victor Entertainment with a major circulation release on August 28, 2008, making it the first Hatsune Miku CD to be sold by a major label. kz has been the sole member of livetune since 2009.
