♫♫ Strung Up From The Sky.... by Pelican ♫♫ Post Metal Instrumental... Thanks Pandora.....

This just caught my ear on the bunker sound system:

Pelican is a post-metal quartet from Des Plaines,^[1] Illinois. Established in 2000, the band stems from their native post-metal scene and is known for their atmospheric and almost entirely instrumental style. They have released five studio albums and four EPs and gained television exposure.
