Jah Division do dub covers of Joy Division songs. Simple as that. You will love it. There is also another group called Jah Division from Russia, who came out first, are more popular and have nothing to do with Joy Division, so don't get em confused. The band I'm posting only has 4 songs from 1 release, titled Dub Will Tear Us Apart.
