The Cliffs of Moher in County Clare, Ireland, are an awe-inspiring sight.  Rising nearly 400 feet above the Atlantic Ocean, they are primarily made up of Namurian Shale and Sandstone, hence the title of this Emerald-inspired composition.  The slip jig in the second part gives way to soaring harmonies meant to evoke the steep drop off of the cliffs themselves.  The traditional sounding melody is augmented by modern harmonies and grooves in the lower strings, and an optional guitar part gives the tune some added zest.
