We do not know much about Nicolo Sanguinazzo, but it has been assumed he was active between 1690 and 1720, and that he was close to Antonio Caldara. On his autographed manuscripts he refers to himself as Olocin Ozzaniugnas, that is his name spelled back to front, a Dilettante di Violoncello. His Book of Exercises represents the great opportunity to go through the meticulous technique of the subtle, graceful, and cheerful Parlando-manner. Dietmar Berger is a German musician and painter. The Cologne-based cellist and gambist is a member of the Delos Trio Köln (with Gudrun Höbold, violin and Hubert Käppel, guitar). His works as a painter range from finely structured Madonna pictures, created under the formative impression of the sacred art of his native city of Cologne, to powerful landscape painting - for him actually a field of experimentation. He has received several scholarships, most recently the Monjoie Scholarship of the StädteRegion Aachen.
