Liquid Tension Experiment (LTE) is an American instrumental progressive metal supergroup founded by Mike Portnoy in 1997. The band initially released two albums, between 1998 and 1999. An extension of their second regular album, with the absence of John Petrucci, was released in 2007 under the name "Liquid Trio Experiment".
