Folks go on to become producers, directors, stage actors, video game voice actors, music label owners, teachers...
It always seems like an interesting story that I would love to know more about, and yet I feel that the act of learning more would itself tarnish their shift, and I try to respect them by digging no further.
I'm a bit of a classic rock / prog rock fan. These bands are getting old, and they sometimes have staff changes as a result of band members dying of old age. Went to a Yes concert recently and have kind of mixed feelings about it. It's like Steve Howe and a backup band. I mean it's great that these older artists "still got it" and want to keep doing what they love, but from the point of view of a fan, maybe it's best to call it a day when your best work is firmly in the past.
I wonder if that is part of why they called it off. Maybe they've created all of the music they could both come up with? Maybe the creativity tank ran empty?
I think I read that the lead singer made the best music when on drugs but has since gotten clean. Unfortunately, the music he/they made sober wasn't as well received critically? Something like that.
The Strokes mainly just hated each other after they got famous. Angles, their fourth album, was famously recorded without Julian ever being in the same room as the rest of the band.
But of course their break up is probably due to a disagreement between the two of them so it wouldn't have been possible if they don't want to spend time together.
