Sonic Symphony

Sonic Symphony is an ongoing concert tour featuring original arrangements of the music of the Sonic the Hedgehog video game series by Sega performed by an orchestra and rock band. A concert also displays footage of gameplay from the series synchronized to the music. The first concert, Sonic the Hedgehog 30th Anniversary Symphony, was presented as a free live stream on YouTube and Twitch on June 23, 2021 to commemorate Sonic the Hedgehog's 30th anniversary. The second and first live concert was presented on October 12, 2022 at the 2022 Brasil Game Show. A live tour, Sonic Symphony World Tour, started on September 16, 2023 in London, England.

History
The Sonic the Hedgehog 30th Anniversary Symphony was announced in the Sonic Central presentation on May 27, 2021. The concert starred the Prague Philharmonic Orchestra performing orchestral arrangements and the Tomoya Ohtani Band and Crush 40 performing pop rock arrangements, with Nathan Sharp as the guest singer. The fan-made Chao Camera mod for Sonic Adventure 2 was used for gameplay footage. The Sonic the Hedgehog 30th Anniversary Symphony was also featured in the 2021 Summer Game Fest. The concert took two years to plan and switched to being shown as a free live stream due to the COVID-19 pandemic. An album of its music was released on September 18, 2021 on the iTunes Store and Apple Music and on other major digital music services four days later.

The concert at the 2022 Brasil Game Show was announced in the Sonic Central presentation on June 7, 2022 with more tour dates to come.

On May 19, 2023, two dates in London, England and Los Angeles, California, United States for the Sonic Symphony World Tour were announced. The Sonic Symphony World Tour is produced by Sega and soundtrec, and presented by MGP Live. Pre-sale for subscribers to the official newsletter started on May 25, 2023 and public sale started a day later. Guest stars are to appear at certain dates. More dates were announced in the Sonic Central presentation on June 23, 2023, with pre-sale starting on June 28, 2023 and public sale on June 30, 2023.

During the Fearless: Year of Shadow marketing campaign in 2024, music related to the character Shadow the Hedgehog was included in Sonic Symphony World Tour's setlist.

Reception
The Sonic the Hedgehog 30th Anniversary Symphony was received positively; Andy Robinson of Video Games Chronicle and Daniel Hollis of Pure Xbox noted such reception from fans. Ash Parrish of Kotaku and Kenneth Shepard of Fanbyte reported that they cried of happiness and the former described the concert as "a heartwarming, tear-inducing, nostalgic happy-time-memory-recalling performance that surpassed all expectations". Stephen Tailby of Push Square called it "a brilliant musical trip down memory lane" and Hollis of Pure Xbox deemed it "the perfect birthday treat" and "one of the best things SEGA has produced in a long time for their trusty mascot".
