Over the weekend, Sega hosted a special charity livestream that went on for 12 straight hours, in which members of the Sonic the Hedgehog Community Team raised money for Extra Life and Children's Miracle Network Hospitals.
During the livestream, the Sonic the Hedgehog Community Team played through a bunch of Sonic-related games, and as donation milestones were reached, special, never-before-seen concept art from a few Sonic the Hedgehog titles were unveiled by Sega.
To be more specific, the concept art that Sega unveiled comes from the beloved Sonic Adventure, Sonic Adventure 2, and Sonic Heroes, and gives us a look at some very early drawings and, well, concept art from the previously titles mentioned, which Sonic the Hedgehog fans will definitely appreciate.
As if that wasn't enough, and as new donation milestones were reached, Sega also shared early demo tracks for Sonic Adventure 2, which are tunes that were composed by the legendary Jun Senoue but were never used in the final version of the game. These unreleased demo tracks are for City Escape, Metal Harbour, Mission Street, and Radical Highway.
Below we've shared the Sonic Adventure, Sonic Adventure 2, and Sonic Heroes concept art that wasunveiled by Sega during the charity livestream, as well as the early demo tracks for Sonic Adventure 2(courtesy of Sonic News Channel), and the part two of the livestream when the concept art was revealed.
