Combining elements of jazz, rock, folk, and classical music, singer/songwriter Konstantin Wecker has long been at the forefront of Germany's Liedermacher movement, a musically sophisticated genre with lyrics that deal in social issues. He released his first album, Die Sadopoetischen Gesänge des Konstantin Amadeus Wecker, in 1972. Critics praised his lyrics, and album by album Wecker built his following. In 1977 he had his breakthrough with Genug Ist Nicht Genug and its popular title track. In 1993 he wrote the novel Uferlos featuring semi-autobiographical tales of illegal drug use. After serving a one-year-and-eight-month jail sentence for possession during 2000-2001, he began writing musicals that were heavily influenced by the cabaret songs of the Weimar Republic and his hero, Bertolt Brecht.
