Robert Lambermont is a Simeon Ten Holt interpreter from the very beginning. Partly due to Robert’s long-standing friendship with Simeon ten Holt, the quartet interprets his compositions according to the composer’s preferences and thus remains closest to the source. Ten Holt even called Robert Lambermont one of the warmest advocates of his music. The pianists regularly gave concerts at his invitation and Ten Holt was the main sponsor of their first CD Canto Ostinato.

By performing the rich musical heritage, the Natalon Quartet meets the versatility of Simeon ten Holt, and pays tribute to his diverse compositions in a unique and impressive way, which are still performed worldwide.
