We're always warned never to judge a book by its cover - but in the case of the cover of KT Tunstall's latest offering, it's impossible to ignore the fact that the singer-songwriter has undergone something of a transformation. Gone is the unassuming persona of the one-time Fence Collective (a group of mostly folk-based Scottish musicians, including James Yorkston and King Creosote) member; in its place is a glamorous, axe-wielding vixen, styled to within an inch of her life and apparently ready to rock your white-leather ankle boots off. Ardent fans shouldn't worry too much, however; much as Drastic Fantastic may look, at first glance, like a homage to ZZ Top or AC/DC, there's nothing more alarming than a perilously-plucked electric guitar on display here. Having sold over four million copies of her 2004 debut 'Eye To the Telescope', Tunstall has taken no risks with her second studio album. Coming across as something of a musical Sharleen Spiteri/David Gray hybrid, her mellow ballads and jangly, Sheryl Crow-style pop rock is as accessible as it is predictable - but, at least this time around, not as enjoyable. Though Eye to the Telescope was a largely pedestrian album, it did spawn some top-drawer singles, most notably Suddenly I See and breakthrough hit Black Horse and the Cherry Tree. There's nothing as striking here, though; most of the 40-minute long album is comprised of mid-paced, melancholic ballads (Funnyman, Beauty of Uncertainty) or bittersweet-yet-bogstandard pop tunes with a rock edge (If Only, Little Favours). The latter tracks see a slight regression to her folk roots, but there's no oomph or real flavour to this album, which promised much, but ultimately, failed to deliver.
