I have a very large collection of box sets which I am a bit obsessed with to be honest but rarely go for the type you mention. I prefer the career retrospective ones with loads of extra tracks. My favourites are the Sandy , Al Stewart and Ian Hunter ones. I have most of the Free Reed ones, and related.

The amazing Wet the Tea at Over Hulton Folk Club on Wednesday.  Big Andy, Adam and Fluff were on superb form.  A great night.

I don't think I've ever bought one.

I don't mind a reissue, if it's of good provenance, and might show some sonic improvement, and/or bonus material,  but I don't need anything beyond ordinary CD  and vinyl.

A box containing
Blu ray,  surround sound cuddly toy etc etc. , is of no interest to me.

Tonight it's Lucca Mae at the Adelphi in Hull, as Alan said nice to see an unfamiliar artist once in a while

I usually buy these , but then question myself why , even the Sandy Denny ones or John Martyn's One World and Solid Air , it is pretty rare to find a demo that you play more often than the finished version
I have the Joy Division ones , still sealed , ditto Led Zeppelin 3 and Houses Of The Holy

After all the bonus material is soon  available on You Tube - and the times you end up buying the original "as released" material - nobody seems to sell "disc 2 only" versions

The Beach Boys would be a case where I do go back to the demos, work in progress
, and I bet Jules does the same with The Who - so he's spot on  in his post , depends in how high a regard you hold a particular album or artist

I'd love it to be Mick Softley.  

Intrigue!

Some, yes. But it depends how obsessive about an artist you are.

There's a plethora of Super Deluxe editions of old albums by Yes, The Police, Black Sabbath, Nirvana, The Beatles, The Rolling Stones etc etc

They usually consist of the original albums, outtakes, demos and sometimes a live album or two.

They all cost a bloody fortune.

Has anyone ever found these to be of great value or interest?

Enquiring minds want to know.

This definitely looks of interest....we just don't actually know what 'this' is yet...
