Eduard Strauss
Rathausball-Tänze op. 438 is a waltz by composer Johann Strauss II written in 1890 in honour of the inauguration of the new city hall of Vienna (the 'Rathaus'). At the opening of the new banqueting hall (Festsaal) on 12 February 1890 two rival orchestras were commissioned to provide dance music for the occasion; the Strauss Orchestra under the direction of Eduard Strauss, and that of rival Kapellmeister Karl Michael Ziehrer who was head of the Vienna House Regiment 'Hoch und Deutschmeister No. 4'.
