„A few years older is the bariton Liviu Holender, also born in Vienna, who sang songs by Schubert and Gustav Mahler on Wednesday afternoon with his fabulously expressive pianist Lukas Rommelspacher.“ (...) Kronen Zeitung

"Lukas Rommelspacher, who had led the Junge Marburger Philharmonie himself for four years before moving to the Frankfurt Opera, was eagerly anticipated. On Sunday evening, he took his place at the grand piano—as the soloist in Sergei Rachmaninoff's Second Piano Concerto. The technical challenges of this work revealed Rommelspacher as a matured pianist who, in every bar, could blindly rely on speaking the exact same language in perfect harmony with the conductor and orchestra, bringing out grand emotions just as skillfully as the smallest tonal details.
The audience honored this gripping interpretation of the piano concerto with thunderous applause; visibly moved, Rommelspacher returned to the stage multiple times and, before the intermission, expressed his gratitude with an encore from Mendelssohn's Lieder ohne Worte.“ Oberhessische Presse

"Lukas Rommelspacher was celebrated with long-lasting applause for his interpretation, which was as sensitive as it was technically brilliant." Wetterauer Zeitung
