Christine Tobin and Sophie Bancroft Tron Theatre, Glasgow *** Celtic Connections resumed its Tron Theatre programme with a double bill featuring two singers who, at one time, might have presented two sets of jazz standards but who have long since moved into their own songwriting and, in Christine Tobin's case, daring adaptations from the singer- songwriter canon, while retaining jazz credentials.

Accompanied by double-bass, fiddle, guitar, percussion and backing vocals, Lothian-based Sophie Bancroft sang of broken romance, friends lost too soon and reactions to women's magazine's idealisation in a sleepy voice that's something of an acquired taste, although the wit and good-time feel of her material went down well with the audience.

Dublin-born Christine Tobin has long been championed in these pages and her development as a songwriter with a distinctive, alluringly-toned voice has, gratifyingly, been recognised through her Best Vocalist success at the BBC Jazz Awards 2008.

With no grand piano onstage and pianist Liam Noble confined to an electronic keyboard, Tobin's overall sound lacked a certain presence, particularly in Stone Cold's atmospheric cityscape, which could have used Noble's acoustic drive alongside guitarist Phil Robson's bite and the rhythm section's effervescence. But her singing was as assured, sardonic and characterful as expected, and her set-list, from Dreamland's hushed voice, cello and keyboard artfulness to Corner of an Eye's sassy, strolling horse groove and No Love No Thrill's full-on swing, highlighted her variety of approach and the consistently high quality of her output.

Her take on Leonard Cohen's Everybody Knows, featuring a blazing cello solo from Kate Shortt, confirmed Tobin's talent for refashioning songs into a style that's vibrantly and utterly convincingly her own. Sponsored by ScottishPower.
