Great Instrumental rock bands/albums?

I already know Paik, Mogwai, and Kinski, Racer X, and "The Target is You" album from Love of Diagrams. I've been into them, because it helps when I'm revising. 
 
Any recommendations? Can even be just albums that were instrumental. Can be any sub-genre of rock.

Explosions in the Sky.

a ton of Apocalyptica songs are Instrumental and awesome.

Liquid Tension Experiment

World's end Girlfriend - Seven Idiots

how about Hot Rats by Zappa?
 
  

Metronomy's first album was instrumental. It was alright.

Joe Satriani - My favorite album of his is Crystal Planet, but all of his albums are pretty good.

@Thrillhouse87: So awesome. Frank Zappa has a couple of strictly instrumental albums that rock.

Zombi is a cool space rock instrumental band

I guess phish are sort of instrumental since they do a lot of improvisation during songs and have quite a few instrumental songs

Thats just rock, but obviously if your looking for instrumental albums, there are tons of incredible jazz albums

well if you're going for guitarists, try Buckethead; for calmer stuff try Colma, for heavier stuff go for Slaughterhouse on the Prairie or Slunk Crime Scene

I'm not sure if these guys are really what you're looking for, but this is The Bakerton Group.
 
  

Rodrigo Y Gabriela -   11-11
spanish guitar style but very much inspired by metal music example alex skolnick :D

Some of their songs do. They don't usually make sense but I suppose they still count as lyrics.

I mean, if it just means that if they don't make sense or whatever, might as well include Sigur Ros in it too

Liquid Tension Experiment 
Scale the Summit 
Animals as Leaders 

It's a little old, but "The Best of Booker T & the M.G.s"

Liquid Tension Experiment Scale the Summit Animals as Leaders   

You guys never disappoint!

This one is probably my favorite song by Maybeshewill. Just don't watch that horrible fan-made video.

Fun Fact: The bass player in Lightning Bolt works at Harmonix.

Gregor Samsa

Liquid Tension Experiment

  This album just came out this year. Fantastic.

@AssInAss: Afro Celt Sound System is more electro, but it's sick as hell. If you're willing to take a risk on some instrumental stuff that's not so much rock, I'd recommend Boards of Canada, Amon Tobin, and most importantly Michael Hedges.

explosions in the sky
do make say think
this will destroy you
godspeed you black emperor!
thee silver mt zion

Wait, you've never heard of GY!BE? If not, go listen to F sharp A sharp Infinity right now.

  Well it's not instrumental but since you have Les Claypool as your avatar then you will probably want to check out the new Primus album, best thing since Pork Soda, right on par with Frizzle Fry.

Explosions in the Sky 
Scale the Summit 
Cloudkicker   (Definitely check this one out.  All of his music is free on his bandcamp.
Red Sparowes 
Pelican 
Grails 
Animals as Leaders 
Electro Quarterstaff 
Godspeed You! Black Emperor 
Russian Circles 
Canvas Solaris 
Mono 
  
EDIT:  Can't believe I forgot Earth, someone above posted them.  Awesome band

Bruce Cockburn put out an instrumental compilation that I rather like.

@chrissedoff: Fuck yes! Earth and Sunn O))) are awesome, although I think Sunn hasn't done to much interesting since Black One. Dylan Carlson continues to dominate as the best act on Southern Lord. I wish Khanate was still around.

Alice is the best song Sunn o)))'s ever done actually (Altar, however, is their best album, and both are after Black One) :P and boris is the best act on southern lord, though earth is quite good

TOE from Japan. Possibly the best band in the world.

@PeasantAbuse said:

@Laketown: I didn't think Boris was on Southern Lord anymore? They didn't put out Attention Please and Heavy Rocks through them.

oh yeah, forgot about that; they're still listed as being a part, there's no reason they can't choose other distributors for certain albums I guess?

but if they aren't, the best band on southern lord is Om.

@Krampus said:

@Laketown: Totally didnt' like Altar, I still have the vinyl but I'm probably going to be selling it soon. That said Boris definitely balls out, the new Heavy Rocks album was especially sweet and their live shows are not to be missed. And actually my favorite Sunn album is La Mort Noir Dans Esch / Alzette which did come after Black One but was the tour for the album so still kind of the same. }:-P Glad there are other fans on this site.

I think the best new boris album was the one they only released in Japan (new album)

Also, I recommend Tortoise's seminal album Millions Now Living Will Never Die.

Perhaps more metal than rock, but Mastodon released an instrumental version of their Crack The Skye album. It's amazing.

(Though I'm upset that what I've heard of their new album is a bit shit.)
