Tastes Differ
Journalist: And what kind of music do you prefer?
Allan: It (1) sounds old-fashioned, Fm afraid, but I really prefer classical jazz and blues.
J: Jazz became a musical phenomenon in the 20th century, didnt it?
A: Yes, this style of music became a worldwide sensation in the first part of the 20th century and (3) stuck with generations. Jazz and blues have very strong (4) influences of African-American musical traditions.
J: Who are your favourite performers?
A: There are many talented musicians and singers, but for me Louis Armstrong and Ella Fitzgerald are the most fabulous.

J: How do you feel about pop music?
A: Im not really (6) keen on pop music. For me its just catchy melodies and silly words. I dont think that most pop singers are well presented (7) either. In other words, I dont like the way they are dressed.
J: You are too hard on them, Im afraid...
A: Perhaps I am. But my (8) value is quality music. Tastes differ, of course...
