A couple of quotes from wikipedia

Sinners (soundtrack)
"The music for the 2025 period supernatural horror film Sinners written, produced, and directed by Ryan Coogler, consisted of two projects produced by Sony Music. The first album, Sinners (Original Motion Picture Soundtrack), featured various genres performed by blues musicians along with the cast members.
The second album, Sinners (Original Motion Picture Score), consisted of the original score composed by Ludwig Göransson, Coogler's frequent collaborator."

"Göransson developed the soundscape from his experience with American blues music, having grown up with his father who was a blues aficionado and listening to blues musicians' as well as filming their concerts."

"They felt challenged in making the music authentic to the movie's 1930's setting, with Göransson saying "What did it really sound like back then? How do we make the audience today feel like they’re hearing something fresh, yet true to the time?" The major problem being there are no great recordings of the 1930s and film footages were lost. The remains of the music from that period, were distorted in pitch, as well as hissing and scratching all over the records.
However, as those recordings were captured live on stage, "it was this energy and atmosphere of live musical performances that we wanted to capture in the juke joint setting."
During the pre-production, Coogler sent Göransson several recordings from the 1930s and early 1940s, particularly the works of Robert Johnson and Tommy Johnson; much of the music had been integrated into the script, and consisted of music from various genres—blues, Irish folk, gospel, jazz and soul music—all of them were performed onscreen."
