I recently started learning What's Going On listening to the isolated track of Jamerson. (yeah, I know it's charted out - but I wanted to get it from listening). This one section was hard for me to grasp at first so I looped it with a click track and then slowed it down. This made it much easier to learn - but it just blows me away to listen to it looped like this. Damn but Jamerson was such a creative player.
