[1] Liquid Tension Experiment was formed by Dream Theater drummer Mike Portnoy after Magna Carta gave him the green light for "whatever he wanted to do".

[2] Portnoy first invited keyboardist Jordan Rudess and progressive rock icon Tony Levin (bass, Chapman Stick) of King Crimson and Peter Gabriel's band to join him.

Two other primary choices, Steve Morse (formerly of Dixie Dregs and Kansas, at that time of Deep Purple) and Jim Matheos (Fates Warning) were also unavailable.

Both Mike and John confirmed on the 5 Years in a Livetime DVD commentary, that Rudess was asked to join Dream Theater largely because of the success of Liquid Tension Experiment, and the chemistry of the three working together.

Mike Portnoy had stated in numerous interviews (and on his web site FAQ) that there would not be a third LTE album, as three of the four band members were also part of Dream Theater and the material would be too similar.

The New York and Los Angeles shows were also released separately on CD or DVD, all through Dream Theater's official bootlegs website, YtseJam Records' subsidiary, Lazy Tomato Entertainment.

The album, called Spontaneous Combustion, was recorded from Mike Portnoy's DATs of the sessions because the original master tapes disappeared before the mixing stage.

[10] On February 10, 2017, Mike Portnoy and Tony Levin reunited on stage in Tampa, FL to perform Paradigm Shift, Acid Rain and Universal Mind.

[12] In May 2020, Jordan Rudess posted a video to the website Cameo stating, in response to a fan's question, that the prospect of Liquid Tension Experiment reuniting "looks very good", with the only barrier being the band members' schedules.

[20] In an interview for Revolver magazine, Portnoy revealed the group had signed a two-album deal with InsideOut, and humorously added that a fourth Liquid Tension Experiment album would probably not take another 20 years.
