You may have noticed the Lessons area of the site disapeared for a couple of weeks. The recent update we made to the site caused some issues with the menu, layout and internal linking of these pages. This has mostly been fixed and an improved category based menu system has been put in place. There is still a small bug with this where the menu doesn't track which category you are currently viewing but we are working on fixing this. Premium lesson content including our Groove Development and Rudiment Workouts have been temporarily moved to the Sheet Music section.
