Born in Leipzig, the son of the concert singer and singing teacher Fritz Polster, he received his first education from his father.
He performed together with the Thomanerchor, whose vocal teacher he was for many years, and made concert tours through Eastern and Western Europe.
Since then he has appeared in many guest roles, as Sarastro in The Magic Flute, as Pogner in the Die Meistersinger von Nürnberg and as Gremin in Eugene Onegin.
Polster was awarded the Kammersänger title and was professor of singing at the University of Music and Theatre Leipzig.
[1] Today he devotes himself above all to the education and professional profiling of young singers with a focus on oratorio and art song.
