On the live album An Evening With John Petrucci & Jordan Rudess John Petrucci and Jordan Rudess played the song "State Of Grace" from the first Liquid Tension Experiment album. Because this was a live performance by the two ex-members the song was played only with acoustic guitar and piano.

The Spontaneous Combustion album is the result of the jamsessions that were held during the recording period of the second Liquid Tension Experiment album. John Petrucci is absent from these jamsessions, as he was with his wife who was giving birth at the time. The album was released under the Liquid Trio Experiment monicker but is essentially from the same band.
