Typically Effusive Praise at the Time: "A creative tour de force, Justice have unleashed an era-defining album for the children of acid house. Never mind Daft Punk, here's disco punk." —The Guardian, 2007
What Happened?: For fuck's sake, we called it "blog house." It was the fickle attitudes of dance music fans combined with the even fickler attitudes of Internet users. It's shocking it lasted as long as it did.
Hype Cycle: 2007–2008
What It Was: The same crappily recorded garage-punk tantrums that have been around since the days of Count Five—but now on trendy indie-rock record labels you've heard of!
Creative Peak: Jay Reatard, Matador Singles '08 
Typically Effusive Praise at the Time: "No wonder they don't care about certain standards of recording quality: They are their own Alan Lomax, immediately 'getting down' the wild, the weird, and the strangely alluring on a single-microphone tape recorder." —Prefix on Times New Viking, 2008
What Happened?: In this accelerated age, a months-too-late MTV News trend piece effectively kills cool dead.
Hype Cycle: 2009
Key Artists: Memory Tapes, Washed Out, Neon Indian
What It Is: An Internet fanbase starving for a sequel to Animal Collective's Merriweather Post Pavilion satiate their appetites via bands with less bread-'n'-butter hustle, but plenty of mushy textures, summery melodies, tape distortion, and names like Ducktails and Reading Rainbow that drive home the fact that, yes, we were kids once . . . remember?!
Creative Peak: Toro Y Moi, "Blessa" seven-inch 
Typically Effusive Praise at the Time: "Remember tape cassettes? No, me neither. Not until Alan Palomo's Neon Indian reminded me how it sounded when a tape played so much it unraveled in the deck." —Pitchfork, 2009
What Happened?: Not technically dead yet, but 90 percent of writing about glo-fi mentions "the summer" in some fashion. And summer's been over for, like, four months now.
