I first went to hear a live rock concert when I was eight years old. My brother and his friends were all 1 of a heavy metal group called Black Wednesday. When they 2 that Black Wednesday were going to perform at our local theatre, they all bought 3 for performance. However, at the last minute, one of the friends couldn't go, so my brother 4 me the ticket. I was really 5 ! I remember the buzz (嘈杂声) of excitement inside the theatre as we all found our 6 . After a few minutes, the lights went down and everybody became 7 . I could barely make out the stage in the 8 . We waited. Then there was a roar from the crowd, like an explosion, as the first members of the band 9 the stage. My brother leaned over and shouted something in my ear, but I couldn't 10 what he was saying. The first song was already starting and the music was as 11 a jet engine. I could 12 the drum beats and bass notes in my stomach. I can't recall any of the songs that the band played. I just 13 that I really enjoyed the show and didn't want it to 14 . But in the end, after three encores (加演), the show finished. We left the 15 and walked unsteadily out onto the pavement. I felt a little dizzy, as if I had just 16 from a long sleep. My ears were still 17 with the beat of the last song. After the 18 , I became a Black Wednesday fan too for a few years before getting into other kinds of music. Once in a while, 19 , I listen to one of their songs and 20 I'm back at that first show. | ||||
