It takes a lot of chutzpah to cover Black Sabbath's eponymous track, by holy hell did Gonga pull it off. They got the incredibly talented Beth Gibbons of Portishead to contribute vocals which results in a haunting rendition of the Sabbath classic.
The track was released in limited quantities on Record Store Day. If you missed it, you are S.O.L.
