What created some of the stranger sounds in the Wolfenstein II: The New Colossus soundtrack? Big sonic sculptures of glass and sheet metal, composer Martin Stig Andersen explains over on Gamasutra. He got to play with the creations of French brothers François and Bernard Baschet, delightfully odd beasts largely played by rubbing crystal rods with wetted hands and amplified through big metal horns, and explains the process as well as how he combined those sounds with other musical elements. The post has many good pictures and things to listen to. Oh, and you might remember Anderson for recording Inside’s music through an actual human skull.
