In modern-day progressive rock, it seems as though there is a new supergroup every few weeks. But long before this was the norm, and before musicians were routinely involved in more than one band, there was Liquid Tension Experiment. Back in 1997, Mike Portnoy (Transatlantic, Sons of Apollo), John Petrucci (Dream Theater), Jordan Rudess (Dream Theater), and Tony Levin (King Crimson, Peter Gabriel), joined forces to create Liquid Tension Experiment. The foursome would release their iconic, self-titled debut album in 1998 and the dazzling follow-up, LTE2 in 1999, creating a dynamic, frantic, and inventive sound all their own. The incredible creativity between the collective would prompt Petrucci and Portnoy to invite Rudess to join Dream Theater, effectively marking the end of this side project.
