Conrad Brumann (~1480-1526) was a German organist.
Biography & Works
Luscinius numbers him among the pupils of Paul Hofhaimer. From 1513 on, he was employed at the cathedral of Speyer, and he is referred to by this title (as "Org von Spyr. m. conrat") in Kleber's tablature.
In said source, his compositions are identified by the initials V. S. (presumably for "von Speyer"), and they include a "Pleni", an untitled "Carmen", a "Praeambalum in Sol", and a coloration of Hofhaimer's "Zucht eer und lob".
