Internationals: Guillemots consist of of a Brazilian guitarist, Canadian bassist, Scottish drummer and Englishman Fyfe Dangerfield After crooning his way into the nation's hearts with the help of a John Lewis advert and cover of Billy Joel's She's Always A Woman, Fyfe Dangerfield has returned to his day job, as frontman of Mercury-nominated four-piece Guillemots. The band's excellent third album, 'Walk The River,' is another exercise in sweeping, orchestral pop. DAVID KOSTEN produced the album. Dangerfield has described it as "music to be heard across the night sky", though last night we had to make do with Camden's Electric Ballroom. This was the second of four secret gigs by the band this month. Not that Dangerfield was hoping to go unnoticed: dressed in a purple suit and green shirt, he looked like he'd taken his sartorial inspiration from the Joker. Behind him, his international band - consisting of a Brazilian guitarist, Canadian bassist and Scottish drummer - provided suitably eclectic backing, from glacial grooves on And If All to jet-propelled pop on The Basket. Elsewhere, future favourite Vermillion was a showcase for Dangerfield's stirring tenor; Made Up Love Song #43 gave everyone a reason to wave the glow sticks handed to them at the entrance; and Trains To Brazil prompted a mass singalong. A set focused heavily on new material tested the patience of the crowd. But then, that's Guillemots: frequently frustrating, occasionally brilliant and now, perhaps, ready to deliver on their obvious potential.
