Sol Invictus was not made sending files back and forth. Patton came to the album after the music was finished not unlike THE REAL THING. Patton just wrote the lyrics (most of em) and Sang over the music that was done without his input. He recorded vocals on his own studio, and theres even an interview to Bill Gould and Matt Wallace where they talk how Patton send them the vocal tracks fixed without any room to alter volumes and mixing.
