The New Jersey Symphony Orchestra is not generally mentioned in the same breath as the Boston Symphony, the Vienna Philharmonic, or the Cleveland Orchestra. But the Newark-based NJSO is now the proud caretaker of 30 of the world’s finest old Italian string instruments, a collection which would be the envy of any of the world’s greatest orchestras. So how do they sound? “Imagine being thirsty and drinking a glass of water – clean, functional, easy to ingest, it satisfies the basic need but little more. Now imagine being offered also a nice, steaming hot cup of the finest Belgian chocolate. Suddenly there is flavor, there is a sequence of sensations… This is something like the difference between the NJSO’s string sound pre-Strads and now.”
