Atlanta audiences last heard von Oeyen just over a year ago in an impressive solo recital at Spivey Hall which included a body of French music and another big work by Liszt: the mighty Sonata in B minor. It was an impressive performance that was insightful and colorful. Von Oeyen brought the same impressive power and musicianship to Thursday’s performance of the Piano Concerto No. 1 [with the Atlanta Symphony]. He and Villaume were a good match, seemingly symbiotic in inspiration and lively execution, with the orchestra musicians fully in league with them. The performance had am energy and momentum that never stalled or stagnated. Afterward, von Oeyen returned to the stage with more Liszt as an exquisite encore: the highly popular Liebestraum.
