Miku Symphony

Miku Symphony was initially a 2-day live concert in association with Crypton Future Media, TWINDRILL, SEGA, and the Warner Music Group and a sequel to the Miku Symphony concerts was performed in the 2016-2017 period. The concerts have been held Yokohama, Osaka, and Hokkaido. Miku Symphony has also celebrated the 10th anniversary of Megurine Luka, Snow Miku, and Kasane Teto with its music performed by the Tokyo Philharmonic Orchestra, widely known as Japan's oldest classical orchestra, and conducted by Hirofumi Kurita, who is also known as the conductor for the Granblue Fantasy Orchestra Concert.

History

The first Miku Symphony was held on August 26, 2016 at the Tokyo International Forum. In attendance was Kagamine Rin and Len's voice provider Asami Shimoda. While waiting for the concert to begin, a Lux commercial featuring Hatsune Miku played for the audience which caused a flurry of posts to social media by attendees. Its theme song, Future Overture (Mirai Jokyoku), was composed by popular Hatsune Miku producer Mitchie M. The song has reached 200,000 views on YouTube.
The symphony was performed to a sold-out crowd and featured many of Miku's and other Vocaloids' most popular songs including "Tell Your World", "Melt", and a medley of ryo (supercell)'s most popular songs. An album titled Hatsune Miku Symphony 2016 - Orchestra Live CD was released November 9 to critical acclaim.

A follow-up to the concert took place on November 24, 2018 (Tokyo) and January 25, 2019 (Osaka). The concert featured 22 songs with 3 encore songs and played to sold-out crowds. Besides the main Vocaloids, derivative character Kasane Teto also made an appearance at the concert to celebrate her 10th anniversary. It was one of the first times that she has performed officially.
Over 20 producers helped organize the event including famous Japanese rock band Bump of Chicken, as well as known Vocaloid producers 40mP, cosMo, Dixie Flatline, MikitoP, Mitchie M, and samfree.
The album Hatsune Miku Symphony 2018-2019 Orchestral Live featured 16 of the songs that were performed on both nights. Featured songs on the album include Roki, Ray (Bump of Chicken), and Taisetsu na Koto (FuwariP) which was sung by all the Vocaloids excluding Megurine Luka.
The concert was advertised heavily by Warner Music Japan and Taisetsu na Koto has reached almost 1 million views on YouTube. Fans embraced the fact that Teto was able to sing along with the other Vocaloids as she has seldom been seen performing in concerts.

A third Miku Symphony was announced in 2019 that will take place on March 24, 2020 in Tokyo. The event celebrates the 5th anniversary of Miku Symphony. Additional concerts will take place in Yokohama on October 17, 2020, and Osaka on November 27.
Tickets range from 5,500 yen for normal tickets, to 16,300 for special seats. Special seat ticket holders will have a unique ticket design as well as limited-edition merchandise.
An album titled Miku Symphony 2019 Orchestra Live was released in December 2019, and features 20 songs spanning 2 CDs. The songs are recordings of previously performed Miku Symphony concerts and celebrates MEIKO's 15 anniversary with a special medley.
