This is part of Gamine's wonderful Christmas EP which you can find on their Bandcamp page: https://gamine.bandcamp.com.
The original footage was from a concert at the 12-Bar Club, a legendary venue in Denmark Street, (also known as Tin Pan Alley) in London. It was intimate (small) and atmospheric (noisy) and Gamine loved to play there.
It became a tradition for them to play there around Christmas time, so on this occasion they thought they'd have a go at a Christmas carol. As you know, Christmas is a time of much merriment, and as you also know, Gamine have built a deserved reputation for exquisite sadness. How could they reconcile these two seemingly irreconcilable concepts? Well, having scoured the canon for a carol in a minor key, it became clear that 'God Rest Ye Merry, Gentlemen' would do the trick.
When they came to record this new version,they changed the title to 'God Rest Ye Merry, Gentlefolk' , as our marketing department discovered that there are not that many gentlemen left, and we didn't want to leave anyone out. It was always our ambition to make something as grandiose as possible, so we hope you enjoy it, but if you want to hear just a piano version, you'll find one on Gamine's Bandcamp page...
