Sometime near the end of The '90s, Dream Theater's drummer, Mike Portnoy, was asked by his company to form a Progressive Rock/Metal supergroup. Said group was composed by Portnoy, his Dream Theater comrade John Petrucci on guitar, the legendary bassist Tony Levin and a then-not-so-notable 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, Ytsejam Records. In 2020, a reunion was announced with, with a third album released in 2021, and possible plans for a fourth album.
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.

Both bands provide examples of:
- Accidental Misnaming: The story behind the name of "Chris and Kevin's Excellent Adventure", where a photographer kept calling Mike Portnoy "Chris" and Tony Levin "Kevin". "Chris and Kevin's Bogus Journey" is, of course, a sequel.
- Bohemian Parody: A band photo for Liquid Tension Experiment 3 is in this style, made more ominous by their hooded apparel (and facial expressions that evoke Cardiacs' take from their Sing to God album).
- 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.
- "Chris and Kevin's Bogus Journey", on Spontaneous Combustion, to "Chris and Kevin's Excellent Journey", on Liquid Tension Experiment. Liquid Tension Experiment 3 also includes "Chris and Kevin's Amazing Odyssey".
- Content Warnings: Done for humorous effect, as shown in the page quote.
- Cover Version: In some of their live shows, they did a Progressive Metal arrangement of George Gershwin's "Rhapsody in Blue". Liquid Tension Experiment 3 includes a studio recording of it as well.
- Epic Rocking: Aside of some exceptions, each and every single of their remaining songs break the 5-minute barrier. The longest, of course, is the twenty-eight-and-a-half-minute "Three Minute Warning".
- Exactly What It Says on the Tin: 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 included samples of a baby's first cry within the track.
- Genre Mashup: Dream Theater-esque Progressive Rock/Metal, mixed in with some Jazz Fusion, a fair amount of Zappaisms, a dash of classical-infused piano, and a teaspoon of electronic music.
- Improv: "Three Minute Warning" and the entire bonus disc of Liquid Tension Experiment 3 are improvised.
- Instrumentals: Everything this supergroup has ever done, may it be Tension or Trio, is this.
- Last Note Hilarity: "When the Water Breaks", which is an epic and ultimately very serious instrumental, ends with a quirky piano solo in the last minute or so.
- Miniscule Rocking: "The Stretch" and "Chris and Kevin's Excellent Adventure"
- Non-Indicative Name: "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."
- Pun-Based Title:
- "Biaxident", which is a play on "by accident" and the medicine "Biaxin", which John Petrucci was taking at the time.
- "When the Water Breaks" may be a Pun-Based Title on the song "When the Levee Breaks", most famous in Led Zeppelin's version on their untitled fourth album. Then, of course, that was mutated to "When the Keyboard Breaks" when, well, Rudess' keyboard broke.
- Serial Escalation: 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.
- The Liquid Trio Experiment song "Jazz Odyssey" is a reference to This is Spın̈al Tap.
- "Chris and Kevin's Excellent Adventure" and "Chris and Kevin's Bogus Journey" are a mix of Accidental Misnaming and references to Bill & Ted's Excellent Adventure and Bill & Ted's Bogus Journey, respectively.
- Liquid Tension Experiment 2 contains a song titled "Chewbacca".
- Spiritual Successor: Levin-Minnemann-Rudess, a 2013 album featuring half of LTE with Marco Minnemann on drums, a very similar type of project.
- Studio Chatter: At the end of "Three Minute Warning" and "Another Dimension".
- Supergroup: Two members from Dream Theater, a future member of the same band who has previously played with many other acts, (David Bowie among them!!!) and a bassist who has played with King Crimson, Peter Gabriel, and Yes.
