In studio

The recording of the music is done by the human musicians and artists, whom the virtual artists are depicted to emulate. In some cases, the singing is done by machines or synthesizer applications, like the Hatsune Miku vocaloid. This is done using the normal in-studio recording process; see Sound recording for a detailed explanation.

In some instances, most notably The Chipmunks, manipulation of voices may be employed, either to achieve a desired vocal effect, or to make it dissimilar to the voice of the actual singer. The manipulation is done by either modifying the playback speed of the vocal track or by putting it through a synthesizer (Vocoding).

Writing and production credits may be assigned to either the virtual band characters, or the human writers and artists involved.

On stage

Virtual bands often perform through virtual concerts, where their likenesses are represented digitally on stage. One of two methods can be employed for live performances. The first involves animating the entire set, with little or no allowance for audience interaction, then "performing" it as is. The major pitfall with this method is the lack of audience interaction, which can be vital during concerts. This is best suited to short performances, where audience response can be predicted.

The second, and more complex, method differs from the first in that allowance is made for a variety of responses and interaction. This means having a wide range of animated sequences ready to play, with matching spoken lines, in response to different reactions.

In both cases, extensive rehearsal is required to synchronize spoken lines and instrumentation with animated action. This can be eliminated by using pre-recorded music and speech; however, doing so also weakens the actual "live" experience.

(Some non-virtual artists and groups have employed a similar technique on some concert tours and performances. DJ Shadow, for example, on his In Tune and On Time tour, had pre-animated sequences, which were played on giant screens behind him while he performed the set. Again, a large amount of pre-tour planning and synchronization rehearsal was required beforehand.^[1])

Early history

While the term had not been coined at the time, Alvin and the Chipmunks were the first virtual band to receive widespread fame. Centered on Alvin, his two brothers Simon and Theodore, and their manager/father Dave Seville, their voices were created by Ross Bagdasarian, Sr., who accelerated the recording of his voice to create the distinctive sound; the process earned him two Grammys in 1959 for engineering.

The success of the Chipmunks spurred on another group, the Nutty Squirrels, to join the ranks. A scat-singing version of Bagdasarian's creation, they made the American Top 40 with their song "Uh-Oh". Their success, however, was short-lived.

Television

In 1968, The Banana Splits premiered on NBC but failed to chart the top 40. A year later in 1969, from rival CBS, The Archies were the first virtual band to appear in worldwide pop charts.

During this time, other television programs, such as Josie and the Pussycats and The Muppet Show, began to include bands as part of the format (in the case of Josie and the Pussycats, the eponymous band was the show's focus). Some of the groups that appeared on these shows released mainstream recordings. Some bands, however, would "break up" after the end of the show's run.

After The Archies, produced by Filmation, became a huge pop hit, Hanna-Barbera started releasing several cartoon TV shows with the adventures of rock bands, such as Josie and the Pussycats, The Cattanooga Cats, The Impossibles, Butch Cassidy and the Sundance Kids, Jabberjaw, and others.

During the 1980s, Hasbro released Jem, an animated TV series featuring two enemy bands with a music video in each episode.

Virtual bands still appear in television: the Chipmunks appeared in their own television show for much of the 1990s, and the Adult Swim show Metalocalypse features the virtual melodic death metal band Dethklok.

Japanese virtual idols

Virtual idols originate from Japan, with roots in anime and Japanese idol culture, and dating back to the 1980s, starting with the Macross mecha anime franchise (adapted into the Robotech franchise in North America).^[2] The first virtual idol was Lynn Minmay, a fictional singer who is one of the main characters in the anime television series Super Dimension Fortress Macross (1982) and the animated film adaptation Macross: Do You Remember Love? (1984). Voiced by Mari Iijima, Lynn Minmay became the first fictional idol singer to garner major real-world success. The theme song "Do You Remember Love?" (from the film Macross: Do You Remember Love?) reached number seven on the Oricon music charts in Japan, and the song has since been covered numerous times over the next several decades.^[2]

The Japanese cyberpunk anime Megazone 23 (1985) took the virtual idol concept further with EVE, who is depicted as a computer-based artificial intelligence (AI) who takes the form of a virtual idol within a proto-Matrix-like virtual reality. Megazone 23 was a success in Japan partly due to the appeal of EVE, and it was later adapted into Robotech: The Movie (1986) in North America.^[3][4] A similar concept later appeared in Macross Plus (1994) with the virtual idol Sharon Apple, a computer program who takes the form of an intergalactic pop star.^[5] The same year, the fictional Japanese rock band Fire Bomber from Macross 7 (1994) became a commercial success, spawning multiple CDs released in Japan.^[6]

The Japanese talent agency Horipro created the first real-life AI virtual idol, Kyoko Date, in 1995. Her creation was inspired by the success of the Macross franchise and dating sim games such as Tokimeki Memorial (1994), along with advances in computer graphics. Her initial announcement drew headlines, both in Japan and internationally, before she debuted as a CGI idol in 1996. However, she failed to gain commercial success, largely due to technical limitations leading to issues such as unnatural movement (an issue known as the uncanny valley).^[5][7][8] Despite her failure, she provided the template for later virtual idols who gained commercial success in the early 21st century, such as the Vocaloid singer Hatsune Miku and the virtual YouTuber Kizuna AI.^[5][7]

In 2007, Crypton Future Media and Yamaha launched Vocaloid 2, with the voice bank of Hatsune Miku. In 2009, Hatsune Miku had her first concert. Other Vocaloids include Meiko, Kaito, Kagamine Rin and Len, and Megurine Luka.

Virtual bands can also originate from video games, as proven by the 2015 Wii U game Splatoon, which features songs credited to various virtual bands, the most notable being a pop duo called the Squid Sisters, who have performed several real world concerts as holograms.^[9][10][11] The game's 2017 Nintendo Switch sequel, Splatoon 2, introduces more virtual bands, most notably Off the Hook, a duo similar to the Squid Sisters. The two duos have performed together as holograms, and has had a special guest, K.K. Slider from the Animal Crossing series, to celebrate the release of Animal Crossing New Horizons. ^[12][13] Prior to it, Nintendo had already made a virtual band composed of characters from Pikmin called Strawberry Flower, to promote the games. Their first single, Ai no Uta, was a massive success in Japan, reaching #2 on the Weekly Oricon Top 200 Singles chart. In 2020, Sega and Sanrio teamed up to make their first collaboration virtual band, Beatcats.

Eternity is a virtual idol group formed by Pulse9. The group debuted on March 22, 2021, with the single "I'm Real". The group consists of 11 members: Seoa, Sujin, Minji, Zae-in, Hyejin, Dain, Chorong, Jiwoo, Yeoreum, Sarang and Yejin.^[14] They are created with artificial intelligence technology, Deep Real.^[15]

Mave: is a virtual girl group formed in 2023 by Metaverse Entertainment. The group consists of Siu, Zena, Marty, and Tyra, who are hyper-realistic, AI-generated members that were created using machine learning, deep fake, and full 3D production technology.^[16][17]
