Introducing Post-rock! Anyone into it?

Might be a long shot cause I've never seen anyone mention it here.
It's my favourite genre, listening to the new Explosions in the Sky album now, fantastic and chill instrumental rock. My fav bands are God is an Astronaut, Isis, 65daysofstatic, Maybeshewill, Grails and Russian Circles.

I'll post some (of my favourite) songs to introduce this to you guys who haven't heard this before, who knows it might be just your cup of tea after all.
