At a certain age, one would like to reflect a bit publicly on the past! Says the man who is known to the general public through his role as the lovable policeman Michi Mohr from the TV series "Rosenheim Cops". And that's what musician and actor Max Müller does - acoustically! On an album together with a book he has written twelve "unwritten letters". To twelve people to whom he "still wanted to say something". Clear, unambiguous and - with a twinkle in his eye! He is musically accompanied by the harpist Elisabeth Daxer with specially composed pieces.
