From an Viriety interview in 2017:
Do you still plan to release the solo album you’ve been talking about since before “The River” anniversary tour?
Oh yeah, I’ve just been caught up in other projects. It’s kind of waiting for its moment. Good music doesn’t go away!
Someone who’d heard it said it sounded like Aaron Copland.
I don’t know if anybody made that particular connection. Really, that record is influenced by Southern California pop music of the ’70s.
Like the Eagles and Fleetwood Mac?
No — Glen Campbell, Jimmy Webb, Burt Bacharach, those kinds of records. I don’t know if people will hear those influences, but that was what I had in my mind. It gave me something to hook an album around; it gave me some inspiration to write. And also, it’s a singer-songwriter record. It’s connected to my solo records writing-wise, more “Tunnel of Love” and “Devils and Dust,” but it’s not like them at all. Just different characters living their lives.
...
You’ve done so much looking back recently, between the book and “The River” anniversary tour and now this Broadway run. Any thoughts on what’s next?
I suppose the [solo] record that I haven’t released. It’s not topical at all — topical writing at the moment doesn’t hold a lot of interest to me. I really got out a lot of what I had to say in that vein on “Wrecking Ball.” I’m not driven to write any anti-Trump diatribe; that doesn’t feel necessary at the moment.
