A true shed in my opinion is not an event where everyone comes to blow their load and try to show how great they are. When I am on tour, I have the opportunity to stop through various sheds with different players, (mostly church cats) and it is always the same. I leave with a headache and usually, it is a waste of my time. I could have been in the hotel catching up on sleep. I have had an opportunity to do sheds where various players came out and even though 2 kits were set up, only one person played at a time along with the bass and percussion. That was the best, because after each player, we asked questions about the execution of certain things. We also heard them play in a musical situation instead of a musical orgie. Pardon my language, but it is true. Clinical situations are usually the best way to learn. Try approaching the shed in a way that there is a focus and a goal. Everyone will grow!!
