M2M are 17-year-old Marion Raven and 18-year-old Marit Larson, both from just outside Oslo. They are both extremely pretty, they have voices as sweet and summery as a weekend from the half-imagined holidays of your youth, and they trade in the kind of acoustic pop whimsy that seems to strike a particular chord with middle-class American adolescents. The fact that they are to appear in the 100th episode of Dawson’s Creek should tell you everything you need to know about M2M.

Basically these are songs by teenagers for teenagers. If you are between the ages of 12 and 17, this acoustic guitar pop will probably sing to the darkest, most secret crevices of your soul: girls will want to be Marion and Marit and boys will want to… well, we all know what boys will want to do.

On the plus side, their voices are top-notch and work really well together, Marion’s Sheryl Crowe-like power combining well with Marit’s more saccharine outpourings. Personally, their shiny, cutesy would-be bittersweet narratives are too frivolous and airy for yours truly and leave me cold. When they sing about feeling like shit on ‘Sometimes’, it’s like your 10-year-old cousin swearing just to appear more grown-up.

M2M are impossible to really dislike: they’re the sweet you can eat between meals, but you know you shouldn’t.
