In some cases referred to as space rock, a genre of music combining styles of prog, ambient rock, indie, experimental, jazz, psychadelia, and some classical. Often utilizing large bands with diverse instruments including brass, chimes, strings, synthesizers, assorted percussion, and winds, many post-rock bands create a very mellow, atmospheric style of music, often climaxing and making use of tonic/dominant/subdominant patterns in classical music and heavily textured sonic layers. Elements of poetry and science fiction are also often incorperated.

Rock: made by musicians who trash the hell outta their hotel room.

Post-rock: made by musicians who arrive at their hotel room to find it already trashed.

A style of music conceived after Beethoven, Bach, and Mozart had passionate, time traveling, inanimate sex with classic Rock albums from Bands ranging from ACDC to Lynyrd Skynyrd. The resulting child has guitar riffs that make Hellen Keller listen again, songs that speak volumes without saying a word, and (If you listen with your eyes closed) the music will give a high so high that you can throw piss bombs on Stealth Bombers as you experience an eargasm so profound that your mind will be blow, reformed, then blown again. In other words: Post-Rock is the musical equal to a Chuck Norris Roundhouse Kick to the unprotected groin.
