Between 1925 and 1932 Arnold Schönberg paid several visits to Catalonia and the city of Barcelona. It was here that Schönberg completed the 2nd act of Moses und Aron as well as his piano piece op. 33b. His daughter Nuria was also born in Barcelona. Now the city has commemorated its famous visitor with a plaque on his house in Bajada de Briz.
This was reported in Revista Musical Catalana.
