Think a New Zealand Spinal Tap meets The Office with music videos. The humor is also very similar in tone to the British Series The Mighty Boosh (from the limited episodes I’ve seen of that).
Basically, two indie rocker guys from New Zealand live in Manhattan and are the sole members of a struggling band with one fan. Their manager holds band meetings in his office at the New Zealand Consolate. Usually once or twice in the episode they break into spontaneous song. You get the idea.
They also have some amazing actors on the show, including Tony-award-winner Frank Wood, and, in one episode, one of the most startlingly good impressions of David Bowie I’ve seen.
