Crush 40, the band that performed the theme songs for past Sonic games such as both Sonic Adventure titles and Sonic Heroes, has put samples of three of their songs that will be on their upcoming EP. While none of the songs are tied to a new Sonic game, one of them is related to the franchise.
The first of these songs, Sonic Youth, heavily references past songs they made or remixed for the Sonic franchise such as Open Your Heart, Live and Learn, His World and Sonic Boom. The as of yet untitled EP will be available on iTunes sometime in the future. The full versions will be performed in Tokyo later this week.
