Sometime near the end of TheNineties, Music/DreamTheater's drummer, Mike Portnoy, was asked by his company to form a ProgressiveRock[=/=][[ProgressiveMetal Metal]] supergroup. Said group was composed by Portnoy, his Dream Theater comrade John Petrucci on guitar, the legendary bassist Tony Levin and a not-so-noble keyboardist named Jordan Rudess. Thus, the seeds for Liquid Tension Experiment were planted.

The band released only two albums before Rudess' definitive incorporation to Dream Theater and the obvious disbandment, at least for studio recordings, since three-quarters of the band were composed by Dream Theater members. It didn't stop Portnoy from releasing several other albums [live recordings] via his own label, [[SdrawkcabName Ytsejam]] Records.

There was a spinoff of this band, called Liquid Trio Experiment, which was composed of the same members, except one of them, who happened to be Petrucci in the first album, ''Spontaneous Combustion'', and Rudess in the second, ''When the Keyboard Breaks''.

Liquid Tension Experiment:

Liquid Trio Experiment:

!Both bands provide examples of:
* CallBack: Liquid Trio Experiment 2's album, ''When the Keyboard Breaks'' is a reference to the track "When the Water Breaks", from ''Liquid Tension Experiment 2''.
* EpicRocking: Aside of some exceptions, each and every single of their remaining songs break the 5-minute barrier.
* ExactlyWhatItSaysOnTheTin: The track that became "When the Water Breaks" was being recorded at the time when John Petrucci's wife went into labour and Petrucci had to leave the studio in the middle of the session. The band even [[ThrowItIn included]] samples of a baby's first cry within the track.
* {{Instrumentals}}: Everything this supergroup has ever done, may it be Tension or Trio, is this.
* NonIndicativeName: "Three Minute Warning", which is a 27-minute improvised jam recorded entirely in a single take. It's so long that the band's primary recording equipment actually ''ran out of space'' and left off the last three or so minutes. The name came from Tony Levin wanting to just play and have fun while the rest of the band wanted to get the structured recording out of the way before they started jamming. He threatened to quit and leave if they "didn't start jamming in three minutes."
* RuleOfCool
* SelfTitledAlbum
* SerialEscalation: Set the standard for many newer progressive bands. It can't be more technically challenging than this. "Paradigm Shift" and "Another Dimension" are both fine examples of this.
* SpiritualSuccessor: ''Levin-Minnemann-Rudess'', a 2013 album featuring half of LTE with Marco Minnemann on drums, a very similar type of project.
* {{Supergroup}}: Two members from Music/DreamTheater, a future member of the same band who has previously played with many other acts, (DavidBowie among them!!!) and a bassist who has played with KingCrimson, PeterGabriel and {{Yes}}.
* WhatCouldHaveBeen: Portnoy wanted several members of other bands to be part of his project, such as [[Music/{{Pantera}} Dimebag Darrell]], [[DeepPurple Steve Morse]] and Jim Matheos, before turning to his Dream Theater partner for the guitar spot.
