Miho and Masumi Hio were solo piano pupils of Elisabeth Vaeth-Schadler and Martyn van den Hoek at the Carinthia State Music Conservatory (Kaerntner Landes- konservatorium) and the Vienna Conservatory (Konservatorium Wien). After earning their diplomas as soloists with distinction, they married in 2005, forming a piano duo and have performed together ever since.
While exploring and expanding their duo repertoire, they pursued a diploma for Piano Duo Performance with Bruno Mezzena at the Music Academy of Pescara, Italy, receiving perfect marks, lauds, and special mention. They are prize winners of several international piano-duo and chamber music competitions in Europe and the USA, including the "Bradshaw International Competition", earning them the opportunity to perform Le Sacre du Printemps in Carnegie Hall, New York.
Their performance activity as a duo began with recitals at the former Japan Boesendorfer Corporation and Sougakudou (Tokyo) in Japan, and has since taken them to many music festivals in Austria, Switzerland, England and Japan. Their concert performances have been recorded for live broadcast on several occasions for ORF- Kaernten.
