Just for the avoidance of confusion, a harmonium and a harmonica are not the same thing (but easy to confuse in translation).
I only recently discovered myself that a harmonium looks like this. They are also known as pump organs because of the bellows on the back.

PJ Harvey fans have waited a long time for this: a centralized meeting point for the singer’s many non-album tracks and orphaned gems. Spanning from her early days, fiddling with a 4-track machine that mentor John Parish taught her to use, to her post-’90s reinventions as a pop-rock shapeshifter, antiwar provocateur-slash-autoharp connoisseur, and television composer, this remarkable, 59-song, six-LP compilation doubles as a shadow history of Harvey’s career, charting her metamorphoses through the songs that didn’t make the cut. It also reveals the one constant—an unswerving intensity that distinguished Harvey from her imitators.

I haven't read through the whole thread so this may have been asked already. Just listening to PJ now and it got me wondering why there isn't a stand alone demos version of her b sides album? I guess some of the released songs such as 'Lying In The Sun' possibly are demos themselves, but songs such as 'Memphis' & 'One Time Too Many' for example don't sound like demos so I assume there are/ were earlier versions of them in demo form? Just wondering other people's thoughts on this?

One last thing to add, I wish they'd have included a demo of 'This Wicked Tongue' (assuming there is one!).

PJ commented on the recently released tracks:

Nina in ecstasy:

That final statement AHAHAHAHH...

okay, this is one of my favorite songs, which when i wrote it i didn't like it at all, so i put it on the b-side. But now i really really like it (giggles) and its title came from a porn movie... which i wasn't choosing, i was in a hotel and you know when you flip through... and i just flipped and said "eew, what's that?!" and it was called "Nina in ecstasy". so, often... it's a true story, and that's often where songs come from and i spoke to other writers they say the same, in fact maybe if you are probably writers you'd know it you might see a title or something and think "ugh... that could be a song, Nina in ecstasy" U2 are really good at that because sometimes when you go down the street you go "it's a beautiful day!" and (general laugh) "it's very quiet on new year's day", that's another one " it's all quiet on new year's day", we can keep doing this as the evening goes on we can keep thinking of a few titles of everyday phrases... (couldn't get what the last sentence was)

"Nina in Ecstasy"- i had purchased the small but mighty Yamaha QY20 (which i still use today), and here i am finding beauty in the lower octaves and soft flute sounds. "Nina in Ecstasy" sounds like a porn film, maybe it was, but my Nina is also lovely, sad, lost lady looking for her mum
