After hearing it last night, the AgesandAges indie rock version of "We Need A Little Christmas" has grown on me. Given the song's general preciousness, singers often sound overly cutesy when tackling it. AgesandAges avoid this by sounding like The Cocteau Twins but with less production gauze on their vocals. The unconventional pauses in the rhythm are slightly jarring at first, but I came to like them fairly easily.
For some listeners, the combo of indie rock and "We Need A Little Christmas" might be reflexively off-putting. Give AgesandAges a chance, though, and you might like how they've made the tune more bearable.
