Bright, unashamedly commercial, but not especially shallow, KT Tunstall's second album, Drastic Fantastic, ought to carry on where her slow-burning debut, Eye To The Telescope, left off.

Last night, at the delightful Wilton's Music Hall (allegedly the world's oldest surviving grand music hall; more verifiably the base for the East Enders who opposed the blackshirts in the 936 Battle Of Cable Street) she launched the record with a brisk, intimate show, interspersing first album favourites with Drastic Fantastic selections.

Tunstall is an earthily likeable performer, full of tall tales, and her songs are made for sharing. Black Horse And The Cherry Tree may have outstayed its welcome, but Suddenly I See sounds as invigorating as it did in 2004.

Of the material she unveiled, Hold On was so similar to Black Horse And The Cherry Tree she might have to sue herself, but she and her lithe four-man band (plus two sulky backing singers) have broadened their horizons.

Blessed with driving choruses, the perky If Only and the curiously Belinda Carlisle-esque ode to plastic surgery Saving My Face already have the air of airpunching future favourites and White Bird - not entirely dissimilar to The Beatles's Blackbird incidentally - was so pretty it almost flew away.

Better still, the solo showcase Paper Aeroplane might have been exhumed from the previous decade (therefore implying Drastic Fantastic songwriting ideas were hard to eke out), but it may well be her career-making ballad. For Tunstall, things are good enough right now. They can only get better.
