94年4月，Symphony X成立于新泽西。之前，吉他手Michael Romeo的自制作个人样带《The Dark Chapter》已经备受好评，也正是这张非正式专辑促成了Symphony X的诞生。第一个加入的是贝司手 Thomas Miller，他曾经与Michael多次合作过。很快，主音Rod Tyler、鼓手Jason Rullo和Michael Pinnella相继加入，乐队成形。他们的首张同名唱片录制于94年秋，同年12月在日本发行。专辑迅速在全球前卫金属圈引起轰动，在日本也取得不俗的评价。距离他们的首张唱片仅仅8个月，Symphony X又录制并发行了第二张专辑《The Damnation Game》。95年初，主音Rod Tyler决定离开，顶替他的是Russell Allen。凭借庄严而协调的人声和古典化的泛音，乐队将前卫金属战线进一步前移，充当起此类音乐向新方向突破的先锋队。媒体和乐迷的反应相当热烈，乐队也计划进一步打开其世界范围的知名度。96年底，Symphony X开始专注于后来大获成功的专辑《The Divine Wings Of Tragedy》的创作。在前一部作品余热未消的情况下，《The Divine Wings Of Tragedy》中乐队更多坚定了走他们自己的道路。专辑后来凭借"The Accolade"和长达20分钟的开始曲深深打动了众多的欧洲专业音乐杂志。在这些杂志的读者回应中Symphony X被夸赞到一个相当高的高度。很快，《The Divine Wings Of Tragedy》被看作当年前卫金属圈的最佳作品。乐队将众多同行乐队远远甩在身后。而这张专辑在商业上也取得巨大成就。乐队并没有沉醉与成功的喜悦，并开始准备下一张专辑，于98年初完成。在他们走进录音室前，Jason Rullo因为个人原因执意离去，Thomas Walling火线入队。这张名为《Twilight In Olympus》的专辑后来被证实是乐队历史上又一个里程碑。销售在一如既往的媒体炒作下依旧火爆，全欧巡演也呼之欲出。但Thomas Walling和Thomas Miller的意外无法成行使乐队赶紧招回了Jason Rullo，另外，还补充了贝司手Andy DeLuca。3周时间，Symphony X跨越了大西洋，脚步遍及欧洲大陆，随行的还有英国乐队Mindfeed。巡演相当成功，演唱会门票在德国、荷兰、瑞士、意大利和法国都被抢购一空，这次巡演更大的扩大了乐队的乐迷群。巡演后， Thomas Miller离队。经过仔细的筛选，Mike LePond入替。99年秋，乐队开始分别在Michael Romeo家里"The Dungeon"和新泽西的"Trax-East"2处录音室进行录音，00年发行《V: The New Mythology Suite》。01年乐队发行过两张现场专集:《Live in Europe》和《Live on the Edge of Forever》。02年乐队发行了大碟《Odyssey》，以当时的标准来衡量可能在曲风上有些过时，但只要你是幻想金属的死忠歌迷，只要你喜欢Symphony X以前的专集，那这丝毫不会影响你购买的热情！Michael Romeo formed Symphony X in New Jersey in 1994. The original lineup of the group also included Thomas Miller (bass guitar), Rod Tyler (vocals), Jason Rullo (drums), and Michael Pinnella (keyboards). They released their self-titled debut late that same year. The next year they put out the follow-up The Damnation Game. 1995 also saw Tyler leave the group, his replacement coming in the personage of Russell Allen. Their next release came out in 1997. It was the critically acclaimed The Divine Wings of Tragedy. In addition to the critical praise, this disc became the groups biggest commercial success yet. Before recording their next album, Jason Rullo left the band. He was replaced by Thomas Walling. With this lineup, the group released Twilight in Olympus. This release garnered both greater critical kudos and greater sales. In a unique turn of events, however, the band faced a new lineup change. Newcomer Walling and bassman Thomas Miller both decided that they were not up to touring for the album. The recently departed Rullo rethought his exodus and came back into the Symphony X fold. Andy DeLuca was brought in on bass for the duration of the tour. After the tour was over, the group found a permanent replacement in Mike LePond. This formation of the group released their fifth album in 2000 with V: The New Mythology Suite.
