“Clarinetist Jonathan Sage’s masterful interpretation [of Steve Reich's New York Counterpoint] suitably highlights that lyrical side in the opening bars, before proceeding merrily on through the repetitive, music-box perkiness of the work, which swells and diminishes polyphonically throughout.”
Paddy Kehoe, RTE Ten

"Jonathan Sage was an agile but intimate soloist in the Mozart [Clarinet Concerto]. For all his twinkling fingerwork, it was the Adagio – taken very slowly – that truly impressed, the pianissimo return of the theme breathtaking."
Martin Dreyer, York Press: November 2010

"The undoubted star of the evening, though, was the guest soloist, Jonathan Sage. Playing the Mozart Clarinet Concerto with the accompaniment of a much reduced orchestra on a basset clarinet (a rarely seen elongated clarinet with an extended range,) he captivated the audience with his graceful and fluent playing of this well-known work, heard for once on the instrument for which it was written. The first and last movements were lively without being rushed, while the slow movement was taken at a deliberate pace which gave the music plenty of time to breathe. But the unaffected and obvious enjoyment with which Jonathan approached the music and the fluid and varied quality of his tone were impressive. Altogether a memorable performance which delighted audience and orchestra alike. May he soon return to Scarborough!"
Frank James, Scarborough Review: November 2010

"The luminous opening of the second movement was beautifully enunciated by Jonathan, the ensemble [London Mozart Players] and conductor responding expressively to the lambent timbre of the clarinet. The final vivace shouldered its way into the calm left by the close of the adagio with precisely the appropriate amount of impoliteness; by this time, soloist, conductor and orchestra were thoroughly revelling in Mozart’s absolute mastery of sparkling musical wit."
Dr Ian Cross, Swavesey Festival: Review June 2008

"...the musicianship and intelligence brought to the performance was exceptional, the technique and realization well-nigh flawless."
Professor Bill Brooks, MA Recital Report: July 2007
