94年4月,Symphony X成立于新澤西。之前,吉他手Michael Romeo的自制作個人樣帶《The Dark Chapter》已經備受好評,也正是這張非正式專輯促成了Symphony X的誕生。第一個加入的是貝司手 Thomas Miller,他曾經與Michael多次合作過。很快,主音Rod Tyler、鼓手Jason Rullo和Michael Pinnella相繼加入,樂隊成形。他們的首張同名唱片錄制于94年秋,同年12月在日本發行。專輯迅速在全球前衛金屬圈引起轟動,在日本也取得不俗的評價。
距離他們的首張唱片僅僅8個月,Symphony X又錄制并發行了第二張專輯《The Damnation Game》。95年初,主音Rod Tyler決定離開,頂替他的是Russell Allen。憑借莊嚴而協調的人聲和古典化的泛音,樂隊將前衛金屬戰線進一步前移,充當起此類音樂向新方向突破的先鋒隊。媒體和樂迷的反應相當熱烈,樂隊也計劃進一步打開其世界范圍的知名度。
96年底,Symphony X開始專注于后來大獲成功的專輯《The Divine Wings Of Tragedy》的創作。在前一部作品余熱未消的情況下,《The Divine Wings Of Tragedy》中樂隊更多堅定了走他們自己的道路。專輯后來憑借"The Accolade"和長達20分鐘的開始曲深深打動了眾多的歐洲專業音樂雜志。在這些雜志的讀者回應中Symphony X被夸贊到一個相當高的高度。很快,《The Divine Wings Of Tragedy》被看作當年前衛金屬圈的最佳作品。樂隊將眾多同行樂隊遠遠甩在身后。而這張專輯在商業上也取得巨大成就。
樂隊并沒有沉醉與成功的喜悅,并開始準備下一張專輯,于98年初完成。在他們走進錄音室前,Jason Rullo因為個人原因執意離去,Thomas Walling火線入隊。這張名為《Twilight In Olympus》的專輯后來被證實是樂隊歷史上又一個里程碑。銷售在一如既往的媒體炒作下依舊火爆,全歐巡演也呼之欲出。但Thomas Walling和Thomas Miller的意外無法成行使樂隊趕緊招回了Jason Rullo,另外,還補充了貝司手Andy DeLuca。3周時間,Symphony X跨越了大西洋,腳步遍及歐洲大陸,隨行的還有英國樂隊Mindfeed。巡演相當成功,演唱會門票在德國、荷蘭、瑞士、意大利和法國都被搶購一空,這次巡演更大的擴大了樂隊的樂迷群。
巡演后, Thomas Miller離隊。經過仔細的篩選,Mike LePond入替。99年秋,樂隊開始分別在Michael Romeo家里"The Dungeon"和新澤西的"Trax-East"2處錄音室進行錄音,00年發行《V: The New Mythology Suite》。
01年樂隊發行過兩張現場專集:《Live in Europe》和《Live on the Edge of Forever》。02年樂隊發行了大碟《Odyssey》,以當時的標準來衡量可能在曲風上有些過時,但只要你是幻想金屬的死忠歌迷,只要你喜歡Symphony X以前的專集,那這絲毫不會影響你購買的熱情!
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.
