Music is the 'standard' garlic for this area. Most of the seedhouses in Eastern Canada sell this variety. By comparison with many of the other varieties, it has small sized heads, but large cloves for it's size. It consider it mild in taste (others may not agree) and a respectable producer. It is a long storage type.
