 Perhaps Benko's most hailed achievement to date is the unearthing and publishing of all known recordings of the Polish virtuoso Josef Hofmann, as well as dozens of historic recordings by other "golden age" pianists.He is also credited with rediscovering and bringing back to public awareness the elderly and reclusive Hungarian piano virtuoso Ervin Nyiregyházi.The recordings that Benko produced, initially for the International Piano Archives, as well as new recordings he made with Nyiregyházi that were issued by Columbia Records, were heatedly discussed for a time due to the pianist's enormous dynamic range and willful interpretive style.
