Ever wonder about the sound of a brake drum or spring coil?  How about a water bottle?  Or maybe you’re interested in the rhythmic structures of the music of India, or a traditional song of the Ewe people of Ghana.  You can see and hear all of these and more when the Percussion Ensemble, directed by Prof. D. Thomas Toner, plays a free concert in the Recital Hall of the Music Building on Redstone campus.
