Check out Manito Percussion. Manito Percussion unites art and science to create sustainable, solid shell drums that speak to the ears, eyes, and hands. Each drum is hand-crafted with the physics of sound in mind. These drums are crafted from wood that New Urban Forestry supplies. Sets of 2 or more drums are most often crafted from the same tree, ensuring even shell densities. What a great way to repurpose trees! You can see more of these great drums here.
