Post Rock

Lately my car has been filled with lots of very long songs, most of them instrumental. I dont know if im unconsciously sick of songs in the standard format or what, but the bands who have been clogging my cd player are:

Red Sparowes
A Silver Mt Zion
Do Make Say Think
Godspeed you Black Emporer!
The Appleseed Cast
Anathallo

Anyone else been enjoy this kind of music?
