Recommend me some bands that do big instrumentals
 

In the vein of Explosions In The Sky, Mogwai, Mono, etc.. Go.

Godspeed You! Black Emperor, Caspian and probably lots more that I can't think of at the moment.

every instrumental band that i listen to (minus a local band) has been listed in this thread +1 so i have nothing for you. my apologies.

Ok I remembered some more - This Will Destroy You, Joy Wants Eternity and This Is Your Captain Speaking.

do make say think, god is an astranout, ...and you will know us by the trail of dead,

stars of the lid and dungen as well.

Pelican

How I forgot Pelican, I don't know. Probably subconsciously ruled them out due to them being that much heavier than the rest of the bands I mentioned.

Caspian is hot. Also checking This Will Destroy You right now and very much enjoying.

godspeed you black emperor
