Dear Mr Kroll,
My congratulations on your 70th birthday. Jazz fans admire you as a talented composer and virtuoso pianist, conductor and arranger. During the years of your creative career you established several highly professional pop groups. Such famous singers as Yury Antonov, Leonid Serebrennikov and Larisa Dolina valued the opportunity to perform with them.
You are appreciated as a wonderful teacher who gives a great deal of his energy and time to training young performers at the famous Gnesin Academy of Music.
I wish you good health, inspiration and success.
My wife joins me in my congratulations.
