Pack of Lies - Playing Over Bar Line is a video guitar lesson presented by Mimi Fox and is sourced from Jazz Performance.
It's critical to get your own internal time together so that you learn to play smoothly over the changes and begin to play over the bar lines in a loose, natural way. One of my favorite players in this regard is Bruce Forman who has an amazing capacity to play super complex lines at breakneck tempos and play over the bar lines at the same time. This style of playing gives the music tremendous freedom.
