This album is by far the best work Guano Apes have put out. I own both their previous albums, but in spite of moments of brilliance (including their debut single, "Open Your Eyes", neither of them really succeeded in channelling the obvious energy of the group consistently into songs that clicked. Walking on a Thin Line finally delivers, lining up song after song of classic Guano Apes. This album is a bit lighter on the manic joke songs than the previous albums, which is probably a good thing. While they have done decent light-hearted songs as B-sides ("Candy Love") and collaborations ("Kumba Yo") in the past, the darker, more sincere material is what Guano Apes do best. Songs like "Quietly", "Storm", and "Kiss the Dawn" on this album are especially successful in this vein. This album single-handedly puts Guano Apes in the ranks of the best rock bands of the world at the moment.
