livetune is a producer group originally formed by kz and Kajuki-P. Their first work, "Packaged", was one of the early works of Hatsune Miku and set a model for the personification of Vocaloids, along with "Miku Miku ni Shite Ageru" and "Koisuru VOC@LOID" (VOC@LOID in Love). Re:package, which featured "Packaged", was the group's first album upon its release at Comiket 73 in December 2008. On August 27, 2008, the album was released professionally under the label Victor Entertainment. It ranked #5 on the Oricon charts shortly after. It was followed by Re:MIKUS, a remix album, in March 2009.
Kajuki-P left livetune in 2009 to work for CAPCOM, leaving kz the sole member of the group. Since then, kz has released numerous albums and written several anime theme songs.
Livetune is currently signed to the label Toy's Factory. Most of the group's music has a "light electronic sound", often complemented by piano. Livetune's most notable Vocaloid works include the aforementioned "Packaged", "Last Night, Good Night", "Yellow" (one of the theme songs of Hatsune Miku -Project DIVA- 2nd), "Weekender Girl" (in collaboration with Hachiouji-P), and "Redial". The vast majority of livetune's Vocaloid songs feature Hatsune Miku.
The circle's most well-known song, "Tell Your World", was originally uploaded to YouTube in December 2011 as the audio for a Google Chrome commercial. The full version of the song was uploaded to YouTube on March 12, 2012. The two videos combined have over eleven million views. Released on March 14, 2012, the Tell Your World EP peaked on the Oricon charts at #4.
