The guest musicians were brought in "to improvise on sections without hearing the full track. With just a basic chord structure at most, they were encouraged to try out anything their hearts encouraged them to, and then, thanks to the emerging digital technology, any results felt appropriate were employed, sometimes in places for which they had never originally been envisioned." Most of the music recorded never made the final album, with Brown commenting "it takes a strong discipline to erase 80% of the music you record. Few have the discipline to get rid of 'stuff'."
