I recall seeing/hearing violinist Roman Totenberg using a curved bow to play Bach back in the 1950s. Does anyone recall this? He, of course, was well known as a virtuoso using the modern bow and in fact gave the premiere of the William Schuman violin concerto which has recently been getting some exposure because of a modern recording by Paul Zukovsky, accompanied by Michael Tilson Thomas. Also, Roman Totenberg is the father of NRP legal correspondent, Nina Totenberg. Scott Morrison
