The music most people seem to accept as “Post-Rock” is instrumental music with long songs featuring rock-ish musicians grooving on a few chords and/or a motif, with a lot of dynamic variation and intensity for as long as an hour at a time.
For most people, the term “Post-Rock” has become synonymous with a certain aesthetic, long, slow-moving guitar-centric (largely diatonic) songs that swell and die out with musical sensibilities largely created in the seventies and eighties.
I want to extend the meaning of Post-Rock.
I think that Post-Rock might include (just a few ideas):
- Music that sometimes incorporates rock sensibilities, but is not made with the goal of being rock.
- A temporary early 21st century terminology for “classical” music which uses rock-n-roll instruments.
- Impressionism in music in the 21st century
- 21st Century music that is agnostic to typical marketing-driven categories such as hip hop, rock, folk, metal, Etc.
- Rock music with a structure informed by electronica.
- Any rock-based music that stands outside of its own genre.
On the other hand, when a friend mentions “post-rock,” I usually assume what they mean is ‘long-boring-electric-guitar-music.’
If Post-Rock is a useful genre, I think we should include bands like The Fiery Furnaces. Otherwise we should just call it “Bedtime Music…”
I think Bjork is post-rock.
