I'm definitely a big old sucker for remixes of James Vincent McMorrow. It's gotten so bad that I actually knew this was going to be Song of the Day before I'd listened.
Okay, maybe it took ~40 seconds to convince me, but wow. When Atu gets going on this track, it really turns into something special.
The album on which you can find the original probably needs no introduction at this point, but just in case: you can purchase Post Tropical here.
