According to this story on Medium with Nic Pizzolatto on several aspects of the show vs. Season 1, he confirms that T-Bone Burnett will be working on music for Season 2 of True Detective. If you have not seen the trailer yet, scroll on down.
HBO: What’s that music on the trailer? Where’d it come from?
Nic: That’s one of several original songs developed with T-Bone Burnett, as original music plays a much greater role this season. The reasons for that are probably best explained by seeing the show, but these songs will be revealed in full at a later date.
Also released recently were posters with each of the 4 stars of the show, Vince Vaughn, Colin Farrell, Rachel McAdams & Taylor Kitsch. Each poster has the line ” We Get the World We Deserve” along with each actor shown from below the eyes to waist level.
The one thing that stands out in Colin’s poster, playing a detective named Ray Velcoro who is caught up in organized crime, brandishing brass knuckles on one of his hands. The new season starts June 21st.
