Erm.. The article.
The last songs he wrote and recorded...
Shelter and TPLOB&S......
But he article doesn't claim the songs on NPP are ghost written, does it? He hasn't finished and recorded songs after those two, but that doesn't mean he didn't write the songs on NPP. Most of No Pier Pressure was written before 2012 and that's no secret. The other, newer stuff on NPP were collaborations. I believe the whole point was that Shelter and Private Life of Bill & Sue are the last "solely written by Brian Wilson"-songs.
