Vulcan's Forge by Seth Gamba features trios for the developing double bass player. They work great for a teacher and students, a trio of students, or a whole group of students doubling or tripling the parts. When preparing these pieces, it is suggested that students learn all parts together and then take turns playing each one. A version for low brass trio is available from the publisher. Movements: The Knight's Armor, Hold the Phone, Vulcan's Forge, Deep Waters, Adagio, Dance Thing, E-minor Blues.
