LEAD VOCALS (1991 - PRESENT)
In 1990, LaBrie learned that Dream Theater was looking for a new singer, so he submitted a tape and was quickly flown to New York for a full audition. The trial went well, and he was chosen ahead of 200 other hopefuls to fill the full-time vocalist position in the band.
LaBrie has since had a significant impact on the vocal melodies on each Dream Theater album, but until recently has had little input on the instrumentation of Dream Theater's music - 2011's A Dramatic Turn of Events features LaBrie in the music credits on three songs. To date he has written or co-written lyrics for at least one song on eight of the twelve albums Dream Theater has released with him in the band, Images and Words, Black Clouds & Silver Linings, Dream Theater and The Astonishing containing none of them.
Asked by Prog-Sphere.com what is his favourite Dream Theater song to play live, James said "The favourite song for me is Scarred, I love performing that live. And... well, Octavarium, that whole freakin’ thing."
GUITARS, BACKING VOCALS (1985 - PRESENT)
John Petrucci is best known as the guitarist, producer, lyricist and founding member of the two-time Grammy nominated progressive metal band Dream Theater as well as the guitarist and founding member of the acclaimed Liquid Tension Experiment. As a solo artist, John is a longstanding veteran of Joe Satriani’s G3 tours, along with Steve Vai, Eric Johnson, Paul Gilbert, Steve Morse and Steve Lukather.

KEYBOARDS (1999 - PRESENT)
Jordan Rudess has been the full-time keyboardist in Dream Theater since the recording of 1999's Metropolis Pt. 2: Scenes from a Memory.

BASS GUITARS (1985 - PRESENT)
Born in Chicago, Illinois, to Korean parents, Myung grew up in Kings Park, Long Island, New York. He played the violin from the age of five until he was asked to play electric bass in a local band when he was fifteen, which he accepted. After graduating from high school he and his high school friend John Petrucci enrolled at the Berklee College of Music, where they met future bandmate Mike Portnoy.
Though Dream Theater is his primary focus musically, he has appeared in a number of other projects through his career. His first was the progressive rock supergroup Platypus, with Rod Morgenstein, Ty Tabor and ex-Dream Theater bandmate Derek Sherinian. After Platypus disbanded in 2000, Myung, Tabor, and Morgenstein recorded four albums as the Jelly Jam.
Myung's favorite bands include the Beatles, Black Sabbath, the Who, Iron Maiden, Rush, Yes, Jethro Tull and Genesis. He cites bassists Geezer Butler, John Entwistle, Chris Squire, Steve Harris, Geddy Lee and Jaco Pastorius as the main influences on his playing style.
DRUMS, PERCUSSION (2011 - PRESENT)
Born in Newton, Massachusetts, Mangini first started playing the drums when he was two and a half years old, being inspired by Ringo Starr of The Beatles. He would practice two to four hours a day and by the time he was nine he was already mimicking Buddy Rich performances. His other influences include Bobby Colomby, Danny Seraphine, John Bonham, Neil Peart and Terry Bozzio.
In late 2010, Mangini, along with Marco Minnemann, Peter Wildoer, Virgil Donati, Aquiles Priester, Derek Roddy and Thomas Lang, auditioned to succeed Mike Portnoy as the drummer for Dream Theater. He had previously appeared on three solo albums by Dream Theater's lead singer, James LaBrie.
Mangini was announced as Dream Theater's new drummer on April 29, 2011, several months after he actually joined. He has appeared on every Dream Theater release since.
