Charlotte Gainsbourg's musical pedigree is no secret. The daughter of French avant-pop provocateurs Serge Gainsbourg and Jane Birkin, her predilection for sophisticated Francophonic pop music is a birthright. Gainsbourg's singing career got off to a contentious start with "Lemon Incest," a wildly suggestive duet with her father about paternal love. Gainsbourg eschewed recording for awhile, concentrating on her acting career until 2006's 5:55, an album-length dream-team collaboration with Air, Jarvis Cocker, Tony Allen and Nigel Godrich. Gainsbourg has recently teamed up with the oddly ubiquitous Beck to record the follow-up. IRM, French for MRI, features Mr. Hansen's writing, production, mixing and backing vocals. Beck's fingerprints are all over this one, and given his recent win streak, that's probably a good thing.
