In 1981, Frans Bruggen and friends founded the Orchestra of the 18th Century, consisting of 50 members from 20 different countries. The musicians, all specialists in 18th and early 19th century music, play on period instruments or on contemporary copies. The wide-ranging repertoire this orchestra performs includes works by Purcell, Bach, Rameau, Haydn, Mozart, Beethoven, Schubert, Mendelssohn and Chopin, and has been recorded for Philips Classics and nowadays for the Spanish label Glossa. In 2014, the Orchestra had to say farewell to Bruggen. This live recording of Beethoven's Piano Concerto no. 4 was made at a concert in the KKL in Luzern (Switzerland) in November 2001 and is only available digitally.
