Oscar Peterson: Unmistakable is a collection of Re-performances created from recordings Peterson made during the '70s and '80s. The Re-performances capture the renowned jazz pianist playing at the height of his abilities, six of which have never been released as audio tracks. The process began with Peterson himself in March 2007: after having heard about the technology, Peterson invited the Zenph team to his home to play examples of their work. A lifelong technology buff, Peterson understood and was enthusiastic about the implications of the Zenph technology on his legacy. Oscar Peterson: Unmistakable extends the acclaimed technological breakthrough featured in prior Sony/Zenph releases of Glenn Gould, Sergei Rachmaninoff and Art Tatum. 　　Zenph employs a proprietary process that uses computer software to transform recorded music back into live performances, precisely replicating what was originally played but with vastly-improved sound quality. To create the Peterson Re-performances, the Zenph team began with video recordings and several unreleased, private recordings of exceptional performances. Recorded in Studio Two at the legendary Abbey Road Studios in London, the team used a specially-outfitted Bosendorfer Imperial Concert Grand piano to authentically recreate the distinct sounds of Peterson's artistry.
