Listen to one musician’s track in isolation on any record (like this one) and you might be amazed at how trivial they sound. Paul McCartney, one of the great bass players, in one the great groups of all time–it sounds a bit like a school music recital.

But we don’t listen to the tracks in isolation, because the isolation isn’t the point.

Human beings care about harmonies. About originality. About the tension that comes from the new. And we care about the dynamics between and among people who are working together.

That’s why we listen to the whole song, not one musician’s isolation track.
