What is "coppelius"

Coppelius is a German band which plays metal on drums, double bass, cello and clarinet. Their name is taken from E.T.A. Hoffmann’s " Der Sandmann". Their logo consists of a top hat with the word "Coppelius" underneath. The band members are Max Coppella ( clarinet and vocals), Comte Caspar ( clarinet, vocals, harpsichord), Graf Lindorf ( cello, vocals), Sissy Voss ( double bass), Nobusama ( drums) and Bastille (Butler, vocals). They are often also accompanied by Prof. Mosch Terpin (technician and harpsichord). On stage they wear formal, old-fashioned clothes, inspired mainly by the Victorian era like many of their songs. This is why they are often referred to as a Steampunk band.
