Campbell and Lanegan performed to a sell out crowd

On one side of the Atlantic, childlike Isobel Campbell, breathless and subtle, and on the other the menacing, dark figure of Mark Lanegan.

Under the roof of the ABC on Glasgow's Sauchiehall Street, they united for Celtic Connections and delivered a Ballad of the Broken Seas.

Campbell, formerly of Belle and Sebastian, penned all but two songs on the Mercury nominated album.

Lanegan, formerly of the Screaming Trees and occasional Queens of the Stone Age frontman, provided Campbell's subtle collection with haunting deep vocals and one track - Revolver.

On stage together, in a rare appearance, these two opposites attracted - Campbell cautious and gentle, Lanegan direct and dangerous - to deliver a memorable set.

Murky world

The crowd reserved much of its appreciation for the mysterious Lanegan.

When he sang Campbell's songs of hopelessness and love in the backwoods he sounded like he was trying to draw her into his murky world.

Permeating his baritone and filling the hall was Campbell's high and husky melody.

Campbell and Lanegan cared for each other in a short sharp seductive set that was over too soon.
