Dream Theater is a progressive rock band whose career has spanned for nearly three decades. The band are known for their excessively long track durations (with the track "Six Degrees of Inner Turbulence" lasting 42 minutes) as well as incredibly complex melodic compositions that often feature the duelling of guitars and keyboards during lengthy complicated solos.

Vocalist James LaBrie has one of the highest – and varied – vocal ranges for a male within the genre which ranges from a ‘chesty low’ sound all the way to a strict soprano sound – E♭2-B♭5 (-B5) to be exact – he has sustained his range over the years despite two vocal injuries.

Guitarist John Petrucci is often cited as one of the world’s top 10 and ranked 6th in Guitar World’s “best shredders” list next to the likes of Paul Gilbert.

Bassist John Myung is known as the shy Asian dude with spider-leg-like fingers – in 2010, Music Radar bestowed Myung as the greatest bassist of all time.

Keyboardist Jordan Rudess has performed and recorded with David Bowie as well as British rock legends UFO’s Vinnie Moore.

Drummer Mike Mangini has worked with Steve Vai, Extreme and even appeared on the Discovery Channel show Time Warp, displaying his drum skills for high speed cameras. He currently holds 5 world records – one including the fastest drum solo without the use of sticks (meaning bare hands). His utmost documented honour of 1200 single strokes in 60 seconds is featured in the Guinness Book of Records.
Guy 1: No way man, Travis Barker and the guys from Slipknot are the greatest musicians of all time!

Guy 2: Pfft! Hardly - let's see them play Dream Theater sets!

The best fucking band in the world. Period.
... Forsaken in The Dark Eternal Night with my Endless Sacrifice to a Dance Of Eternity. I will rise Another Day to be In The Presence of Enemies, and then Lie to You Not Me. I' Burning My Soul in Hell's Kitchen while begging In The Name Of God to Just Let Me Breathe and Take Away My Pain. If you try to Pull Me Under, I will Raise The Knife and make you The Root Of All Evil. As I Am like Perfect Strangers to you, I will give you a Goodnight Kiss before you Disappear and get somebody to to see Through My Words .. because It's Only A Matter Of Time before I end up Beyond This Life just like A Fatal Tragedy with a Strange Deja Vu. Take a look at yourself .. in The Mirror. That's Dream Theater.

The Gods of Progressive Rock, and a band consisting living legends:
John Petrucci (Guitars and vocals - overwhelming)
James Labrie (Vocals - Better than best)
John Myung (Bass - great but seems to be by his band members)
Jordan Rudess (Keyboards, Continuum and lap steel guitar - petrucci's music twin)
Mike Portnoy (Drums, Percussion, Vocals - One of the greatest drummers)

Every1 should get DT's new album, Octavarium, it ROCKS!!
Dream Theater rules over the popular fucks in terms of 'music'(but music is all that matters!) and cannot be compared to crappy-rappy music shits.

Bitch: "yo dumbass, rap is the best, dream theater sux shit"
Me: "Well, that's cuz u don't know real music, and suck the mic 24/7, cocksucker.
Bitch: "O.."
Me: "Yeah you STFU, or i'll call Bush"\

Probably the only band in the history who can write 30+ minute songs that people will actually listen to.
Guy: "Dude, are you done listening to that Dream Theater song yet?"

Dream Theater Fan: "No, I'm only 25 minutes in."

Guy: "!!!"

An amazing Progressive metal band, whom have been going for over 20 years. Not a mainstream band, therefore not very popular or even wellknown to the present public, but kicking ass. Each member proves to be a god at their instrumental talent.
Me - Lo, Do you like Dream Theater?
Person - Dream Who?
Me - Nevermind...

The best band Ever. Progressive Metal, they have two 24 minute songs (A Change Of Seasons, Octavarium) And one 42 minute song (Second Cd of Six Degrees of Inner Turbulence)
Popular Rock bands wish they had the skills of the gods (if they have heard of them) They are so awsome John Petrucci went with G3, each member is highly skilled. I was an atheist, and these guys has caused me to convert to their cult following. Most people cannot begin to fathom how much these guys rock. They could be their own supergroup.
Average Joe: Omg I just bought Senses Fail tickets!

Me: *Bitch Slaps him with an Octavarium CD*

Average Joe: Holy Shit dude. I felt the intense power of that band without even listening to it! I've found the light! Thank you from that terrible fate my comrade!

Me: Not a problem, now lets go and scalp those tickets and get Dream Theater tickets.
