Answer
Rostropovich and Richter formed a legendary musical partnership that spanned over two decades. They first performed together in 1945 and quickly gained international recognition for their exceptional musicianship and profound interpretations. Rostropovich's technical mastery and emotional depth on the cello perfectly complemented Richter's virtuosic pianism and intellectual rigor. Together, they pushed the boundaries of their instruments and the cello-piano repertoire, leaving a lasting legacy on classical music.
