来自马里兰州的Good Charlotte，成军也已进入第十个年头，曾赢得加拿大Much Music音乐奖“最佳国际团体”与MTV录影带音乐奖“观众票选最爱”，宣染出一片年轻旺盛的气焰，并迅速成为年轻学子疯狂追逐的焦点。
主唱Joel及吉他手Benji Madden这对双胞胎兄弟，自小就对音乐有着浓厚兴趣，他们每天都花上好几个小时在演唱和创作音乐上。他们与贝斯手Paul Thomas、鼓手Aaron Escolopio共同创作表演，之后吉他手Billy Martin加入团中，Good Charlotte终告成立。这支名字来自某本儿童读物的乐队开始闯荡乐坛，于2000年推出首张同名专辑，赢取一张金唱片。接着于2002年发行《The Young And The Hopeless》，两年后发行《The Chronicles Of Life And Death》，光在美国销售就加总突破四百万张。如今的Good Charlotte，不再是过去困苦的小孩，他们已然是富有知名的摇滚明星。但是这一切荣耀光彩的景况并不代表了他们已经忘记来时路，忘记自己的根本。他们此刻更是努力在他们的音乐事业上，让他们的梦想能够永久持续下去。他们仍旧坚持于他们固有的流行朋克风格，在自己的最新专辑中加入了更多流行元素，并被赋予了富有冒险、意想不到等诸多定义。
