• "…blown away by the John Oliver piece" [Traces performed by the Vaughan String Quartet, Edmonton, AB, April 2, 2016] - Dave Selsky

  • "A tour de force of orchestral writing, this work is a delightful listening experience." - Elaine Keillor, CAML Review on Forging Utopia

  • "I hope you ask John Oliver to write more trio work for you. His cycle was stunning!" - William Aide, pianist, on recent recording of Eternity Gaze for erhu, piano, and guitar by PEP. (See Recordings)

  • "In The FiveRing Concerto, the composer introduced a lot of effects; the overall composition is very dynamic, sometimes even harsh and intense, as if attacking all the listener's senses. At the same time, it is a distinctly musical piece, whose inspiration - different winter sports - guides the listener through different creative processes and compositional ideas. It is another exceptional piece that introduced Canadian music and left it in the warmest memory of the Croatian audience."
