When Steinmetz was fourteen, his grandfather moved from Antwerp, Belgium, to Israel and taught him many traditional Vizhnitz tunes which influenced his musical style.

Steinmetz sings religious Jewish songs, with the lyrics often being taken directly from scripture or prayers, and is known for the great emotion he puts into his music.

[2][3] In accordance with his ultra-Orthodox interpretation of the Jewish laws of modesty, he never performs to mixed audiences of men and women, unless there is a mechitza (separation).

This was challenged in the local courts with a judge recommending that the audience be split three ways with the addition of a mixed gender area.

[10] Steinmetz said that he found the controversy “infuriating” and that he had received praise from Haredi politicians Aryeh Deri and Moshe Gafni.
