Director's Cut/Anniversary as promo tool: Nirvana

Picked this up from the Mojo website: Nirvana are issuing the 'director's cut' of Heart Shaped Box, borrowing a standard tool from the film toolkit to promote back catalogue sales:

An extended version of the Anton Corbijn-directed video for Nirvana’s Heart-Shaped Box has appeared online ahead of the release of the 20th Anniversary edition of In Utero (due out on September 24).
We’ve called on MOJO’s forensic unit to compare this Director’s Cut with the original film. Their analysis suggests three key areas where this new version differs, namely, more appearances from the small girl in the robe, more of the fleshy-body-suit woman and more Nirvana at their visceral best.

The magazine is running its own tie-in, using the 20th anniversary of its release as a hook too:

And if that’s not enough of a Nirvana rarity for you, you can always check out the band’s original 1988 recording contract with Sub Pop. As the label says, “Six hundred bucks well spent. Not that we had it at the time.”
And don’t forget – you can read Jon Savage’s mammoth 1993 interview with Kurt Cobain in the current issue of MOJO magazine – on sale now.

THE POINT IS...
Good example of another strategy used by record co's/bands to promote back catalogue, but also a good idea for you to consider making a vid for a track released 10/20/25 (etc) years ago, as there is likely to be increased media attention and possibly a re-release/re-packaging/compilation to go with it.
You can look for inspiration by viewing past charts (eg at http://www.officialcharts.com/archive/music/). Another great site, which features all the vids (with iTunes purchase links) for top 20s of each year in the 70s/80s/90s (US charts) is http://www.songs-old.com/Top-20-Songs-Billboard-Charts.html.

Here's the vid cited:

Concept/Perf Vid featured on multiple YT channels

Longish post title: interesting example of a lyric-free rock vid blending concept (with a suggested narrative; concepts tend to have some narrative glue - narrative vids are those which directly tie into the lyrics) and performance. Comes close to getting sleazy (your reading may be that it falls over that line), and though the editing's generally sharp there are some obvious points where cutting to the beat, or simply greater shot variation would be good.

To my eyes there's a strong Anton Corbijn influence here (and it reminds me of the 2012 IGS vid for The Swing Movement in some regards, especially the use of focus-pulling and switching), with (to these eyes) an evident nod to Nirvana when the upbeat section kicks in with a splash (tho' you could also take this as a horror note in what could be alternatively read as a David Lynchian, filmic text).
What I also found noteworthy was the promotional strategy: they've either set up multiple YT channels or just got fans who've opted to put their vid as their channel's autoplaying featured vid. I came across it via another promotional strategy: adding other YT users/channels as contacts. Simple psychology: the suitably burnished ego of most YT users will coax them to add every contact to boost their numbers (I always click through to suss out who/what has requested this ... thus still making the strategy a winner!).

As well as the official CQ channel, Feeeppe, and mary1982next had CQ as their set vid at 20.11.12 and had all added me as a contact within a couple of days in Sept 2012.
