Rockbox by Brian Slawson is an enthusiastic piece for percussion ensemble designed to develop the "weak" hand of developing drummers and percussionists. For many players, the left hand is weaker and underutilized to compensate. This piece seeks to address that with all descending lines starting and ending with the left hand. Intended as a tongue-in-cheek throwback to the disco era, Rockbox is a piece that students and audiences will love! It is a great tool for young percussionists and college methods courses, as well. Rockbox ships as a printed, professionally bound score and includes individual parts in PDF format for printing or tablet viewing.
