In a little street in Brussels, two identical buildings stand together. In one of these buildings lives the famous concert pianist Martha Argerich. Next door we find the Tiempo – Lechner family, renowned by their lineage of piano prodigies. The matriarch and pedagogue Lyl Tiempo, her renowned children Sergio Tiempo and Karin Lechner; and Karin’s young daughter Natasha, only thirteen years old. Natasha, the latest promise on the “pianists street”, has to live up to the legacy of four generations of great musicians.
