One of the DVD extras in series one has the shows' creator interviewing the soundtrack guy (who also sings the theme tune). They talk about how they wanted to make the music sound like Louisiana but without having any 'Louisiana' music. They actually mention the criticism about East coast hip hop featuring in one of the scenes (Crowleyhead getting exposure), and pooh pooh the idea that just because characters would most likely be listening to southern tracks- they have to play southern tracks.
Yeah, I fuck with the soundtrack/score dude, T-Bone Burnett, a lot TBH. He's responsible for the music for The Hunger Games movies (so he is the genius who decided to put Laurie Spiegel in there and thereby basically got her a decent check; he also constructed this really borderline GOTHY/apocalyptic song with Taylor Swift and some of her labelmates) and the song selections of the Nashville series (all actually written by professional Nashville singer-songwriters).
I think his soundtrack work is great in the context of the show, and obviously the Wu-Tang use is perfect for the scene. The line about them saying 'conjuring Louisiana without actually necessarily being Louisiana artists' is cool; it reminds me of say, the inadequacy of vision where David Simon's "Treme" is concerned.
At the same time though, if Burnett had been exposed to something like Concentration Camp, or even generally popular southern rappers like 8Ball & MJG or UGK... It could've conceivably gotten the atmosphere just as well.
I'm not mad at that though. I wonder if there are Louisiana people who find the application of Les Claypool's cartoon white trash aesthetic onto Louisiana cool or weird.
But yeah, Burnett is one of my favorite people in 'media' music right now. I'd love to yell at him for an hour. Hopefully he sticks around this season.
