Perhaps if Eddi Reader had stuck to pop, she might just about be remembered as the crystalline-voiced housewives' choice who topped the pop charts in 1988 with Fairground Attraction's Perfect. However, she has displayed remarkable longevity by moving between other genres. Her latest show skips from pop (Perfect, Patience of Angels) to Celtic folk and Lucinda Williams-style country rock, songs by Robert Burns and, on her new album Peacetime, songs that hopefully suggest alternatives to pelting the world with bombs.

The timeless redhead's constant is her voice - which, at 47, sounds even more crystalline and perfect than ever. However, Reader's trump card is a salacious down-to-earth wit that allows her to take her audience with her. Perhaps Burns's 18th-century Brose and Butter might seem a little highbrow if Reader didn't helpfully explain that it's about masturbation. "The boys are going to fire away at it," she shrieks.

The "boys" are a consummate band, including Fairground drummer Roy Dodds, longtime cohort Boo Hewerdine and folk protege Kris Drever, who provide the butt for Reader's saucy jokes and handle the Glaswegian's moods with note-perfect precision.

Prisons is a shimmering pop wonder. Declan O'Rourke's Galileo is a spine-tingling love song. The Afton, from her new album, is a stirring homage to an Ayrshire river which remains beautiful "even with the trolleys and nappies".

A spectacular scat remodel of Elvis Presley's Mystery Train suggests yet another new direction. However, it is perhaps most wonderful to see her fail to keep a straight face singing Burns's Charlie Is My Darling, a traditional, stirring, romantic stomp about, according to Reader, "how easy it is to make love in a kilt".
