Johann Sebastian Bach's music has been performed by musicians of his own time (including himself), and in the second half of the eighteenth century by his sons and students, and by the next generations of musicians and composers such as the young Beethoven. Felix Mendelssohn renewed the attention for Bach's music by his performances in the 19th century. In the 20th century Bach's music was performed and recorded by artists specializing in the music of the composer, such as Albert Schweitzer, Helmut Walcha and Karl Richter. With the advent of the historically informed performance practice Bach's music was prominently featured by artists such as Nikolaus Harnoncourt, Gustav Leonhardt and Sigiswald Kuijken.
