Two leading performers, who are also effective verbal exponents of their art, talk

about the origins of jazz, its relations to rock, and the likelihood of finding good

audiences in Europe as compared to the United States; but they also turn delightfully to the keyboard from time to time to let their fingers do the talking. BT: "Rock and roll... was a conscious effort by primarily white artists to perform in a way that was black." ... DW: "One difference between jazz and rock is that jazz is not a song-oriented music.... Rock is based on songs, and jazz hasn't been, really, for fifty years. There are lots of people who sing, but that's not the same thing. Jazz is an instrumental music. You can't sing an Art Tatum solo and you can't sing a Beethoven symphony."
