Johann Heinrich von Weissenburg or Giovanni Henrico Albicastro? Those who knew the former knew a professional military man who served as a Captain of Cavalry in the War of the Spanish Succession in the early 18th century. Those who knew the latter were a much smaller group — they knew the talented amateur musician — a violin player and composer, who went by Giovanni Henrico Albicastro as a pen name for writing music. This is some of the Beautiful Music composed by the part-time musician.
