As a child Manfred Siebald learned to play several musical instruments, including the violin, the viola and the piano. Along with his studies at the Philipps University of Marburg of Marburg he took instruction in harmonisation and singing. As early as 1970 he was conducting the Youth for Christ Choir and singing in the Christ Singers. He also brought out his first single - ``Meinst du wirklich, es genugt?'' - at that time. In 1972 he published his first solo album, entitled Da steh ich nun. Siebald gained an international following with his performances at Eurofest '75, the international youth conference and evangelistic crusade which was organized by the Billy Graham organisation in Brussels. Siebald has often been compared with the singer-songwriter Reinhard Mey for his style, and sometimes with Graham Kendrick for his influence on Christian music in his country.
