Prelude On Lasst Uns Erfreuen is a work by renowned contemporary composer Nico Muhly for Organ. Lasting around 6 minutes it was composed in 2007. The composition was dedicated to Alison Shafer commemorating 25 years of service for Christian Lane and the Evangelical Reformed United Church of Christ Frederick Maryland. In the September/October 2015 issue of Choir & Organ Stephen Farr writes that this work 'applies a variety of motivic treatments and a corresponding variety of rhythmic twists to the well-known melody...would be effective in either concert or liturgicalcontexts'.
