Spontaneous Combustion is an album by progressive metal group Liquid Trio Experiment, and is the result of the studio improvisations of Liquid Tension Experiment which occurred during John Petrucci's hiatus, while he spent time with his wife while she was giving birth.

The remaining trio of Mike Portnoy, Tony Levin and Jordan Rudess continued to make music during this period.

The song "Chris & Kevin's Bogus Journey" is not a reference to Portnoy and Petrucci's former Dream Theater bandmates Chris Collins and Kevin Moore, but rather to the track on Liquid Tension Experiment's first album entitled "Chris & Kevin's Excellent Adventure", which is itself a reference to the band's photographer's habit of calling Mike Portnoy and Tony Levin "Chris and Kevin", even after being corrected several times.

It is also a reference to the 1991 film Bill & Ted's Bogus Journey, the sequel to Bill & Ted's Excellent Adventure.

The song "Jazz Odyssey" is a reference to the movie This Is Spinal Tap, in which Spinal Tap experiments with an improvisational song of the same name.
