Nexus (percussion ensemble) in the context of "Percussion ensemble"

A percussion ensemble is a musical ensemble consisting of only percussion instruments. Although the term can be used to describe any such group, it commonly refers to groups of classically trained percussionists performing primarily classical music. In America, percussion ensembles are most commonly found at conservatories, though some professional groups, such as Nexus and So Percussion exist. Drumlines and groups who regularly meet for drum circles are two other forms of the percussion ensemble.
