My First Concert

Hi, I’m Lori. I play the guitar in a band. I started learning about two years ago and the group got together last year. Anyway, a week ago we had our first concert and I want to tell you about it. It was at the local town hall, not far from my

school, where we practise, and near the hotel where my mum works. The concert was to make some money for three local charities that help nature and animals. There were two other groups on as well as us. Another group wanted to play too, but their singer was ill so they couldn’t do it. The town hall is big enough for about three hundred people, but unfortunately there were only about eighty people there (and thirty of them were our friends and families!). Anyway, my friend’s band played first, then us and finally a band of older teenagers, who were really good. My friend’s band was OK, but they made a lot of mistakes. They played a lot of pop songs, which most of the audience liked, but I can’t stand. We play rock and the older kids’ band plays hip-hop, so there was a good mix of music. When we started playing, we could see that the audience liked pop more than rock. Some of them left the building and didn’t come back. Then some others started shouting. At first I thought it was because they liked us, but then I realised it was the opposite! To make things worse, I fell off the stage in the middle of our fourth song and hurt my leg! I didn’t have to go to hospital, but it still hurts. We’re doing another concert in two weeks’ time – I hope it goes better than this one!
