This video from 2005 shows a young Robin Schlotz performing one of the most notoriously difficult (female) soprano arias in the whole operatic repertoire.
Mozart’s aria from his opera The Magic Flute is famous for its terrifying high notes and extreme melodic leaps, but the lederhosen-clad Schlotz is more than able to tackle it.
Bravo, the young Robin!
However, like many internet child stars, Schlotz has sought to reinvent himself. Check out this video of Robin from 2013, where he totally proves his voice did break.
