Black Rainbow
From threeA Wiki
Black Rainbow is a fictional band from the Adventure Kartel universe that Zomb MD was in during his college years. Zomb MD is only known member of the band and the specific style of music is unknown. Since this band is featured in a t-shirt on both Bleak Mission and the Zombkin, there has been speculation that Bleak Mission and Zomb MD may have grown up together, been friends, or that Bleak may also have been a member of the band.
According to Ashley Wood, the band started each show with the manifesto: "you will find nothing but a bucket of shit at the end of the black rainbow" [1]
