unused songs were later released in the YtseJam Records release The Falling into Infinity Demos. The material that made it onto the album proper was released as Falling into Infinity, which received a mixed reception from fans who were more familiar with the band's earlier sound. While the album was moderately progressive-sounding, tracks such as "Hollow Years" and "You Not Me" prompted some to believe it was the dawn of a new, mainstream-sounding Dream Theater. Overall, the album was both a critical and commercial disappointment. Although Portnoy did not speak out publicly at the time, he later revealed in the 2004 DVD commentary for 5 Years in a Livetime, that he had been so discouraged during this period that he had considered disbanding Dream Theater altogether. During the European leg of the Touring Into Infinity world tour, two shows were recorded for a live album titled Once in a LIVEtime, in France and The Netherlands. The album was released at around the same time as the video 5 Years in a Livetime, which covered the years from Kevin Moore's departure to the Falling into Infinity promotional tour. Derek Sherinian's departure, addition of Jordan Rudess, and Metropolis Pt. 2: Scenes from a Memory (1999–2000) In 1997, Magna Carta Records' Mike Varney invited Portnoy to assemble a progressive 'supergroup' to work on an album, which would become the first in a long string of side-projects for the members of Dream Theater. The lineup consisted of Portnoy on drums, Petrucci on guitar, Tony Levin on bass, and keyboardist Jordan Rudess, who had finished with the Dixie Dregs. The band assumed the name Liquid Tension Experiment, and would act as a medium through which Portnoy and Petrucci could once again court Rudess to join Dream Theater. In 1999, he accepted an offer to become the third full-time Dream Theater keyboardist, replacing Sherinian. With yet another new member, Dream Theater entered BearTracks Studio once again to write and record their next album. As a result of an ultimatum from Portnoy, the label gave the band complete creative control. The band began by revisiting the follow-up to "Metropolis–Part I", which had been partially written during the Falling into Infinity sessions but which had not been completed or used on that album. They decided to expand the 21-minute song into a complete concept album, with a story revolving around themes such as reincarnation, murder and betrayal. To
