L'estat (acc. to the widow's maid), Ariel Pink's Haunted Graffiti

The title pretty much sums up this song, it's just utterly bizarre. From the opening seconds, you are entered into this strange odyssey of sounds which are wonderfully textured so the song really does benefit from a high volume on a decent speaker system. I love loads of little details, for example, the little popping sound you get at 3.15 in the song. The effect of the guitars remind me of old Megadrive games, and the song is just as fun as Sonic was when you were 7 years old. I've never paid any attention to the lyrics, but they are just as surreal as the sound:

"Madame Morse Estate
Fell one summer's day
Rolling down to the water
Where the madams made pants
To her mother, she loves her"

No idea what this is about, but I can't get enough. Round and Round, from the same album was Pitchfork's #1 song of 2010, but I think this also measures up as one of the songs of the year.
