Newman's the main songwriter and he's a good one, but he's kind of a shitty singer, and his solo stuff from what I recall doesn't play to his (limited) strengths. Then again, it's been a while since I heard any of it.
I quite like Whiteout Conditions, their third-most-recent album (2017). One of them (I think Newman) called it "bubblegum Krautrock" and that's not a bad description. This is probably my favorite song off it.
