Pinchas Zuckerman played the “world’s most expensive violin” on March 21st in Moscow. Maxim Viktorov paid $3.9 million for the Guarneri del Gesu last month and he lent it to Zuckerman for a private concert at the Great Kremlin Palace and a performance at the Tchaikovsky Moscow State Conservatory. Zuckerman, when asked to compare the violin to his own Guarneri, said that would be like comparing two Rolls Royces, “your Rolls might be a Silver Shadow or a Corniche, but they’re both wonderful cars.”
