It's a question eventually faced by most pop stars: what does one do when it is no longer seemly to trawl Soho sex shops for inspiration? In the midst of what he calls "the Indian summer of my career", Marc Almond feels it especially keenly. So the 47-year-old singer has launched a week-long residency that incorporates the music of Jacques Brel, Lou Reed and others who have captured that wretched-morning-after feeling.

The Almeida's brick backdrop and a red spotlight go a long way toward evoking Almond's spiritual home, 1930s Berlin. His queasy relish for the dark side also figures in his choice of almost comically apt material, such as Satan's Child, When Bad People Kiss and A Hustler's Tango. This is Almond as we have long known him - but with rueful maturity as an extra ingredient. Wistfulness and regret hang heavily, established straight away by a half-dozen tracks from his last album, Heart on Snow. These Russian "romance" songs, sung on a bare stage to black-and-white footage of Soviet-era banned artists such as gay singer Vadim Kozin, are desperately poignant.

The second half, backed by a band, is the down-and-dirty part. This is the cocktail-blues sleaze of I Cover the Waterfront and Brel's Amsterdam tempered with the certainty that Almond will pay for it in the end. His voice, deeper and truer than in his Soft Cell days (which don't get a look-in, by the way), makes them his own. The night ends happily, though, with an optimistic Strangers in the Night, sung to a swooning girl fan. Still utterly a one-off, Almond should be cherished.
