The average length of time between Neil Finn albums is 35 months or about 3 years...
Interesting! Not 100% convinced on your maths though at this stage. I reckon it would be a lot shorter than that.
What album do you consider the first true Neil Finn album? True Colours? See Ya Round? Crowded House?
Lightsleeper represents Neil's quickest turnaround yet, coming out just 11 months after Out of Silence.
I counted just 6 months between One Nil (April 2001) and Rain (October 2001).
Not sure if you're counting Rain but as far as I'm concerned it's as fully-fledged of a Neil Finn studio album as anything else.
Also just 9 months between The Sun Came Out and Intriguer, if you want to consider The Sun Came Out in the mix that is. As far as Neil's contributions go, it's probably more of an EP.
But then again as far as his Split Enz, Finn Brothers and Neil & Liam Finn projects go, you could argue Neil's contributions are also effectively EP-length, with him contributing only around 50% of the songwriting and vocal duties.
And could Woodface count as two records when you take into account the fact that with all songs considered it could have easily been a double album?
So many questions... haha
it was a long 43 months between Dizzy Heights (2014) and Out of Silence (2017) - the longest Neil has ever taken between records.
Since you don't appear to be counting Rain, and would exclude One All (since it's effectively a re-release of One Nil) then the 39 weeks between One Nil and Everyone Is Here also comes close, as does the 35 weeks between Temple of Low Men and Woodface and 35 weeks again for Time on Earth and Intriguer.
Anyway great analysis, it makes for some interesting reading!
