“Indie Rock” means music released on independent record labels - labels that are not subdivisions of major labels and aren’t owned by larger coporations. That’s why I take issue with people when they ridiculously refer to bands signed to major labels as “Indie” artists.
But “Indie Rock” also refers to a specific musical genre that no longer exists - it specifically refers to the 1990’s brand of rock music released on independent labels that was grouped together by a specific aesthetic. I’m talking about the big bands of the era like Sebadoh, Pavement, Guided by Voices (the holy trilogy), Beat Happening, Archers of Loaf, Built to Spill, and so on. “Indie Rock” implies that nineties brand of favoring lower production values and “lo-fi” recording techniques (as a reaction to the overproduction of late-eighties and early-nineties mainstream music) wrapped around guitar-centric pop songs. There were of course many variations; bands like the Apples in Stereo and Olivia Tremor Control favored emulating the british invasion while later twee groups like Belle and Sebastian and His Name is Alive looked to sixties folk-pop for inspiration. Bands like the Magnetic Fields and Land of the Loops embraced synth-pop, albeit in a consciously wink-wink nudge-nudge ironic way, while Built to Spill and Karate broke with the popular “amateurism” fad and embraced guitar heroics. Regardless of those different strains and divisions, there was an overriding aesthetic gel to the whole thing; it just made sense that completely different bands like Butterglory, the Magnetic Fields, and Superchunk were on the same record label (Merge).
Those days are no longer. The entire indie scene completely changed and melted into what can best be described as a “generic hipster” scene now, if it can even be called a scene. I think that, between file-sharing and the complete genre-melt that we’re in the middle of, there’s actually no scene at all to speak of. There are a lot of independent bands out there, a lot of completely different bands on the same indepedent labels that share no aesthetic sensibility in the way that the nineties bands did (the New Pornographers, Laura Cantrell, Interpol and Matmos on the same label, Matador), a lot of bands that used to be independent bands living quiet lives on major labels (Built to Spill, Modest Mouse), and so on.
Basically, the phrase “indie rock” no longer has any meaning.
This whole hipster melt thing is interesting, though, because everyone looks the same - kooky - and you can’t tell who’s a complete fraud or what anyone’s into. The guy with a messenger bag, scruffy beard, and ironic t-shirt might be a hip hop beatmaker, a filmmaker, a rock band guy, or just someone that sort of likes the Decemberists and Modest Mouse but doesn’t really know anything about anything other than that. The chick in weird glasses with kooky that looks like a total artster might be a performance artist, a punker, a recovering rave chick that’s into noise from Fag Tapes, or she might like Kelly Clarkson and Avril Lavigne and just look the part. Crazy! it used to be a lot easier out there, because there was a scene and things like “indie rock” meant something.
Personally, I think we’re better off now, but it’ll change more.
