Something is holding back an "only-if-you-must" two-star review, and right now we're not sure what it is. Such dithering is probably a good thing, and it is to Una Keane's credit that we can't decide whether she's in thrall to the often charming, always likeable kookiness of Rosie Thomas, or whether she's a low-rent Tori Amos in cahoots with a superannuated Kate Bush. Such fluctuation is fine, however, particularly when there are tracks as out-there beguiling as The Sailor's Waltz, Down by the River, Antarcticaand Victory. Keane's background as a classically trained pianist certainly adds textures to the tunes, while her voice – equal parts irritating, winsome and just-right – can either lift or drop the listener, depending on what singing style she applies. For all the critical prevaricating, though, there's something about Keane that keeps coming back. Three stars today, then. Two tomorrow? Maybe. See unakeane.com
