It must have been daunting for J.S Bach’s musical sons to work with his huge shadow. The fact that four of his children succeeded in becoming important and influential composers is both remarkable and proof of how extraordinary these men were. C.P.E and J.C Bach are perhaps the most famous of them, and of the other two, J.C.F and W.F, it is Wilhelm Friedemann (1710-84) who perhaps came closest to his father as a composer.
He was born in 's-Graveland, North Holland and studied organ and harpsichord from 1947 to 1950 with Eduard Müller at the Schola Cantorum Basiliensis in Basel. In 1950, he made his debut as a harpsichordist in Vienna, where he studied musicology. He was professor of harpsichord at the Academy of Music from 1952 to 1955 and at the Amsterdam Conservatory from 1954. He was also a church organist.wiki
"Bach's unfinished Art of Fugue, published for still-debated reasons in open score, has been performed and recorded in dozens of different instrumental versions. But this one, by the veteran Akademie für alte Musik, founded in the former East Berlin, is unique; few others have differentiated the fugues by instrumental forces deployed, and perhaps in none has the overall effect been quite so kaleidoscopic as this one. (…) The sound engineering, a product of Berlin's Teldex Studio, is a major strong point." ~allmusic
Between 1720 and 1723 J. S. Bach composed two sets of clavier pieces in two and three parts, designed to form part of the “Clavierbiichlein”, an instructional work intended for his son Wilhelm Friedemann, with provision in each set for fifteen compositions…
…The Akademie für Alte Musik Berlin scores a triumph with these fresh, powerful, and ever-stylish performances that even long-time connoisseurs shouldn’t be without. And if you’re new to C.P.E., you’re in for a pleasant surprise.
