"Cross-genre collaboration projects such as this are usually a mixed bag of results and Sisyphus is no different. On their own merit, each of these artists have made memorable and original music with Stevens perhaps adding the most bona fide indie star power of the bunch. It is also Stevens whose contributions sit most jarringly in Sisyphus' eccentric mix ... There are certainly fun, playful moments, often thanks to Serengeti's wry, conversational style like on "Lion's Share," which sounds like three friends having fun in a studio and in the end, that's probably what this album is all about. Taken as a musical statement, Sisyphus works fairly well at times, but it's the kind of collaboration no one asked for and much like their mythological Greek king namesake, getting all three artists' styles to gel is a bit like pushing a boulder eternally up a hill".
