Article: -For five days, Edmonton's Downtown Park is transformed into one huge stage where artists are able to share their talents, and where people are able to celebrate and enjoy themselves. Since its beginning in 1980, the Edmonton Folk Music Festival has been commemorating the true feeling of what folk music is all about and that's the traditional togetherness that is felt when people gather to share stories and feelings through song. This year will be the sixth year when volunteer Riedel will be offering up her time to the festival. "People coming off a busy spring and summer have a moment of relaxation," Riedel said. "It's really easy to relax, and it's great seeing family and friends have fun together." These families and friends come from all different kinds of musical tastes. People who take pleasure in Blues are there, so are people who love Bluegrass. This festival does its best to develop everyone's musical interests. With so many years of experience, the festival has become a well-oiled machine, and does whatever it can to make attendees feel as comfortable as possible. There are free water stations throughout the venue for people to fill up their travel cups. When people buy food, reusable dishes are given a $2 plate fee, but that is returned when the plate is brought back. The festival has completely sold out of tickets, and in record time. But with big names such as Van Morrison and Jakob Dylan, it's easy to see how that was going to happen. There is no parking area during the festival, so using the Park & Ride system or Edmonton Transit is highly recommended. A bike lock-up area is provided and will be available Thursday until Sunday one hour before the gates open until 45 minutes after the gates close. The Edmonton Folk Music Festival begins on Wednesday, Aug. 4 with Van Morrison playing the special donation fund concert, and will finish up on Sunday, Aug. 8.

Article: Music comes in many forms;most countries have a style of their own. Poland has its folks. Hungary has its czardas. Argentina is famous for the tango. The U.S.A.is known for jazz,the type of music that has gained worldwide popularity. Jazz is an American contribution to popular music. While classical music follows formal European tradition,jazz is rather a free form. It is full of energy,expressing the moods,interests,and emotions of the people. It is breaking and exciting with a modern sound. In the 1920s jazz sounded like America. And so it does today. The origins of the music are as interesting as the music itself. Jazz was invented by American Negroes,or blacks,as they are called today,who were brought to the southern states as slaves. They were sold to farm owners and forced to work long hours in the cotton and tobacco fields. This work was hard and life was short. When a Negro died his friends and s would gather and carry the body to have a ceremony before they buried him. There was always a band with them. On the way to the ceremony the band played slowly,solemn music suitable for the situation. But on the way home the mood changed. Spirits lifted. Everyone was happy. Death had removed one of their members,but the living were glad to be alive. The band played happy music. This music made everyone want to dance. It was an early form of jazz. Music has always been important in Negro life. The black,who were brought to American from West Africa,had a rich musical tradition. In the fields,they made up work songs. Singing made the hard work go faster. And when they got to Christianity,they made lovely spirituals,which have become an everlasting part of American music.

Article: As the mobile phones so widely appear in our daily life, someone said it would be cool if you didn't have a mobile phone nowadays. It might be true to some extent, but as for an adult, a mobile means contact. It connects your work, relatives, friends, etc. It should do great deeds for us. Months ago, my uncle gave his dear son a phone, because my nephew's school is far from his home. He can only come back once a term, and the phones haven't been so expensive yet. However, someone has criticized the young people for playing on mobiles, but not using. They are fond of sending messages, taking pictures and so on. They buy expensive, high level and fashion types for showing. They play on the mobiles day in and day out ..... Holy cow! So, what happens to youngsters around you? Do they have a phone? What do they use it for? Do you think it's necessary for teenagers who are still in school to have a phone? POSTER 1: In my view, mobile phones are only a tool for communication purpose, just like any other tools which have the potential to be misused. In my opinion, I can see young people using it for security reason, emergency purpose, etc. If the parents can afford to pay big phone bills for their kids, well, that's their business, like the old saying goes, _ --- Mary Smith POSTER 2: From psychological point of view, teenagers are more likely to be relaxed or pleasure-oriented. They would like to make something different. Buying brands that are considered "COOL" is important to them. They want others to like and admire themselves, and sometimes, even exaggerate their own personality to show off. This can be seen as a kind of psychology during this certain range of age. --- Dick Gates Currently, people should tend to be more sociable, and age should not be seen as a barrier for teenagers to own their phones. They also need to set trends on the social circuit . But here parents should play an important role in controlling their children about how to use the phones more properly.
