Keyboardist Christopher Hogwood established the Academy of Ancient Music in 1973, using as his model an ensemble that had been founded in 1726 to perform music that was at least 150 years old.
Thus, Hogwood's orchestra was one of the first in modern times to perform Baroque works on Baroque instruments. Hogwood chose members who were not only masters of their instruments, but also scholars of performance style of the period. The orchestra quickly gained recognition for its authentic performances and recordings, or at least stirred up musicological debate. In 1978, it spawned a Classical period orchestra to perform the works of Mozart and Haydn and their contemporaries. That orchestra has recorded or taken on recording the complete symphonies of Mozart (the first such cycle on period instruments), Haydn, and Beethoven, and the complete piano concertos of Beethoven and Mozart. Recorded for Decca, these were under the direction of Hogwood, who also led recordings of Mozart's La Clemenza di Tito, Haydn's Orfeo ed Euridice, and Handel's Rinaldo, all of which were prize-winners and featured Cecilia Bartoli.
Andrew Manze stepped down from his post in 2003, as the Academy celebrated its 30th anniversary. The ensemble marked the year by also celebrating the Corelli anniversary and the 60th birthday of John Tavener in special concerts, and by beginning an exploration of the music of Mendelssohn, once again expanding its musicological horizons.
