The Lamento "Wie bist du denn, o Gott" was composed by Johann Christoph Bach (1642-1703) of the Arnstadt line.
Not by Johann Ambrosius Bach's twin brother Johann Christoph Bach (1645-1693) as the editor of the pdf version states.
Also not by Johann Christoph Friedrich Bach (1732-1795) who is accredited here.
