"There's a difference between overdubbing and me doing sonics," remarks Lanois, "though doing treatments is also a musical process, not an engineering process. In 'Rumblin'', I took some samples of Neil's guitar, and built those sounds, and then I removed the guitar in the opening of the song. That section repeats later in the song.
