Cardrossmaniac 2 with thoughts on "revival spiral" (Lauren Cochrane's coinage), the Revival of Everything, and a term new to me, "swagger jacker":
Re. "The Revival Of Everything", he says: "I thought this revival started somewhere in the mid to late 90s. The interweb was taking off. The Beastie Boys were making eclectic records likeill Communication that had funk, soundtrack, rock, jazz, rap, latin, reggae, world, punk and many other vibes. Grande Royale, The Beasties own magazine was getting into all sorts of things that seemed to not make sense at the time. All of a sudden in the streets it seemed like anything from any era was up for grabs and hey why not mix and match eras too in fashion, music, furniture etc. This is where today's atemporality was forming."
I think it's something that people often feel about their era - I felt like that a bit in the mid to late 80s. And I'm finding that similar feelings of malaise, directionlessness and omnidirectional nostalgia surfaced in the middle Seventies. It's a recurrence, rather than how it feels when you're in it, which is that the time you're living through is uniquely going to the retro dogs... Then there's another surge phase and retro-eclecticism and concurrent multiple revivalisms can be banished to the margins again.
Re: "Swagger Jacker", he notes that it's a term for "rappers who mimic other rappers unique style, flow and, well, their entire vibe really. It appears that in 2006 Cam'ron had a tune called 'Swagger Jacker'that was a comprehensive dis of Jay Z. Cam'ron juxtaposes Jay Z's lyrics and flow against the swagger of Biggie, Snoop & Slick Rick to make the point that Z ain't too original."
Back in the day they used to call that biting - biting someone's style.
