Since then he has released 4 records on City Slang and Caroline International. The new album “The Horror” will be released June 8th 2018. Always keen to set himself new challenges, THE HORROR is, among other things, Gropper’s homage to Sinatra and the concept albums of his 1950’s heyday. Beside his career he has worked as a soundtrack composer, scoring five feature films – including work for Wim Wenders – a television series, and several theme songs for TV shows, alongside composing for the theatre and working as a producer for a number of artists, ranging from platinum-selling rap-albums to chamber-pop singer-songwriters. All of which shows the range and diversity of his prodigious – and prolific – talent.
