Giovanni Henrico Albicastro was the italianized name of Bavarian composer Johann Heinrich von Weissenburg (c. 1660 – 26 January 1730), a talented amateur musician who published his compositions pseudonymously.
 Albicastro came from the village of Bieswangen, near Pappenheim in central Bavaria, not far from the village of Weissenburg ("White Castle", thus "Albicastro").
 Johann Gottfried Walther included Albicastro in his "Musicalisches Lexicon" (1732) under the mistaken supposition that Albicastro came from Switzerland; consequently he has often been included in lists of Swiss musicians.
 He might be classified as a Bavarian-born composer of Italian music that was published in both the Protestant and Catholic Low Countries.
Brides of Destruction was a short-lived American hard rock supergroup from Los Angeles, California, formed in 2002.
