JOE Bonamassa, the great blues guitarist, has such a relentless schedule - studio work, tours, side projects - that he's like Jack Bauer in 24: when, you wonder, does he sleep, eat and do other everyday things?

He has been working on his 11th solo album but, in the meantime, he and his fellow Grammy nominee, singer Beth Hart, have released their third joint project, a live collection recorded last summer.

Its songs are typical of the kind that influenced them when they were setting out: alongside Strange Fruit and Nutbush City Limits, we find Buddy Miles's Miss Lady, Tom Waits's Chocolate Jesus and Etta James's Something's Got A Hold On Me, not to mention couple of more recent songs by Melody Gardot.

Not surprisingly, in view of the ecletic tracklisting and the meaty presence of a horn section, the mood and the tempo switch often: the upbeat workout of that Etta James song, the poignant cover of Gardot's Your Heart Is As Black As Night, the atmospheric reading of Strange Fruit and the standout tracks, I'd Rather Go Blind and Al Kooper's I Love You More Than You'll Ever Know, both with great Bonamassa solos.

Hart is in fine voice throughout, as befits someone who has often been compared to Janis Joplin.
