     Like many people you may be dreaming of a career as a rock and roll star. There are two ways to go about

getting one. First there is the traditional (传统的) way. Find some friends and form a group. Learn to play the

guitar or the drums. Write your own songs. Spend hours arguing about the band name. then go out on the road.

     The next step is to spend a year or two touring. If you are any good, the crowds will get bigger. In the end

an artist from a record (唱片) company may come to a show. If he or she likes you, there may be a deal (交易). This is the path traditionally followed by bands in the music industry. Success means fame and wealth. And

failure gives you some interesting stories to tell your children.

     Over the last few years a different path to success has become known. Boy bands like Boyzone and girl

bands like Spice Girls don't come together on their own. They are created by managers and record companies.

Their image (形象) is strictly controlled. Professional (专业) song writers usually write their music. This is a

convenient arrangement (安排) and the public seems to love the result.

     Though boy and girl bands have become very popular recently, there is a long tradition of making music in

this way. In the early 1960's an American businessman called Berry Gordy founded Motown Records. Motown

is short for "motor town". The record company was based in the city of Detroit, where thousands of African-

Americans had moved to work in the car industry. They brought with them a cultural tradition of writing and

performing music. This style later became known as "soul music". Berry Gordy was a diamond miner.

Motown stars were not just given songs to sing. They were also taught how to dress well and speak properly.
