Over the past year or so I've noticed the "post-rock" label thrown around a lot. Bands like Godspeed You Black Emperor, Mogwai, Sigur Ros, A Silver Mt. Zion, etc. that have this whole instrumental soft ambient-to-loud crescendo thing going on. The only one I own thus far is Sigur Ros' ( ) which is like a mix of Cocteau Twins and My Bloody Valentine.
Why is it called "post-rock?" It sounds more like a sect of progressive rock to my ear, or experimental ambient (sort of like Eno records with conventional instruments replacing the synthesizers, if that makes any sense). Does anyone know what industry wag started the trend of calling it "post-rock?"
On a related note, if there are any Godspeed fans in the audience, which album do you see as their best?
