I watched S01-03 originally on Netflix here in the US- looks like it's no longer available. But glad to know S04 is out! I'll have to hunt it down.
It also has an incredibly stylish 20's intro and the soundtrack is great too! Def. one of my favorites- if you like Peaky Blinders, it has a similar level of production quality and art direction.
I can't believe anyone would downvote the Black Keys! (This was at 0)
