livetune is a producer group originally formed by kz and Kajuki-P. Already friends attending the same university, they formed the group so they could combine their Vocaloid tracks on a single CD , since neither had enough to warrant individual releases. The livetune name is derived from Auto-Tune and Ableton Live. The group became associated with Redjuice when he presented kz with fanart for "Strobo Nights"; Redjuice later designed livetune's early album jackets and created the PV for "Last Night, Good Night"(with Hatsune miku).
