I don’t know about your experience, but there are tons of viral videos I have seen over the years, but there are also gaps where it seems everyone-but-me has seen a video.

This might be one of those videos.

I watched a lot of Letterman over the years, but most of it was when the show was on NBC. Over the last year or so, the Letterman YouTube channel has been posting lots of “favorite moments” by the staff — I’ve watched most of them, if not all. In his video, Drummer Anton Fig off-handedly mentions a performance by Future Islands, which is then followed by a very brief clip.

Wow. I sought it out and it was amazing. Vocalist Samuel T. Herring look eerily similar to a young Marlon Brando, and dances in a very hypnotic way. He occasionally drops his voice into a demonic growl. It all works.

Another nice little bonus is how clearly delighted Letterman is by the performance. It was great seeing someone who is often a little guarded just exuberantly enjoying a moment.

Was I the only person to not see and hear this? I hadn’t even heard of Future Islands before. It’s embarrassing!

Anyways, sorry if you’ve already seen/heard this video. If you haven’t, please enjoy.
