Perhaps better known for their insanely great, groundbreaking videos than their music (which is equally great, for the record), OK Go return after a four-year layoff with one of the most confident-sounding albums of their career. Throughout their career, the group has basically reinvented themselves with each album, refusing to settle on a specific style of music. Hungry Ghosts is no different although it does bare a mix of the hallmarks heard on their previous records. Relying upon an undercurrent of electronica throughout, the group’s pop roots prominently heard on “The Writing’s On The Wall” and the climatic “The One Moment” co-exist nicely with the funky “I Won’t Let You Down” and the bombastic album opener “Upside Down & Inside Out.”
