On October 23rd 2007, a CD of jams from the 2nd LTE recording sessions will be released under the name Liquid Trio Experiment. The album, Spontaneous Combustion, will include studio improvisations from the trio of Portnoy, Levin and Rudess which occurred while John Petrucci was with his wife and newborn daughter, Kiara. A few songs from LTE2 were spawned from these jam sessions including "914," "Chewbacca," and "Liquid Dreams." Once Petrucci returned to the group, he added in his guitar parts, sometimes learning improvized Jordan Rudess solos note-for-note in order to double them and create a more composed feel for the song.
* Tony Levin - bass, Chapman stick
