Hi! A week ago I been on the concert of rock music in New York with my friends. It was great! There It was many my favourite groups. (My Chemical Romance, HIM, Placebo, Artic Monkeys) I'd like to saw them on the concert. It saved my money because I paid 170 dollars and listen to many groups rather than one. It's a plus. But I did not like atmosphere there. There were a lot of people and a terrible crush! I hardly did not lost my friends out of sight. Generally if despite the disadvantages it was the best thing i ever seen!
