Excelcia Music’s Ensemble Builders for Percussion, Six Ensemble Works Playable With As Few As Four Percussionists, is a set of six newly composed pieces from percussionist, educator and composer Robert Clayson. Written at an accessible level, this collection, sold as a full set, is a definitive introduction for the percussive ensemble. Playable with as few as four percussionists, Ensemble Builders for Percussion can be expanded up to a full-size percussion ensemble, and 13 percussion parts are included.
