The album title DEM DEUTSCHEN JAZZ, also the name of one of its tracks, is a homage to the strength of the contemporary German jazz scene and there is no doubt that this new album does it great credit.

It can also bring smiles to the faces of discerning listeners with its humorous references to a range of jazz influences, not least bebop and swing.

It's typical Berlin.
