Stefan has garnered a string of superb reviews for his performances of the Mendelssohn Violin Concerto with the Australian Chamber Orchestra. The Sydney Morning Herald raved, "Jackiw returned to end the concert with an earnest, breathless and strikingly accomplished performance of Mendelssohn's Violin Concerto in an arrangement by Richard Tognetti for 10 string instruments plus soloist. Jackiw's sound is lean and transparent, with thrilling glow in the upper register and characterised by brilliance and refined color." The Australian reported, "Sustaining a pure, focused tone and crystalline articulation, violinist Stefan Jackiw was an outstanding soloist. His fluid line and flowing bow strokes penetrated right to the heart of the concerto’s cantabile soul and he met the work’s technical challenges brilliantly." And The Daily Telegraph stated, "Jackiw’s performance of the Mendelssohn concerto was the second stunning reading of this glorious work in three months for local audiences following German violinist Christian Tetzlaff’s appearance with Sydney Symphony Orchestra. Jackiw is an exciting talent who is on the verge of classical music stardom."
