Reworking a popular piece of classical music is often frowned upon, but that is exactly what Walter Murphy does with A Fifth of Beethoven, a disco adaptation of Beethoven’s Fifth Symphony. It became incredibly popular in 1976, and was featured in the movie Saturday Night Fever. Although classical music and disco may seem as distant to each other as possible, classical music full of nuance and variation and disco relying on repetition, the differences are what make the mashup of styles work.
There are a few versions of the song, but my favorite is a performance by the BBC Concert Orchestra. There is something inherently funny about watching a full orchestra take a disco hit so seriously.
