bands whose members' solo projects did not precipitate a break-up or split

fair enough I guess the band didn't split up directly because of his solo album (although Wikipedia says he left to focus on his solo project, but that's Wikipedia, and there is no citation), but they split up anyway so not exactly a continuing success

yeah, they split up because the remaining other singer had writer's block and threw tantrums when the drummer kept bringing in fully-written instrumentals. so they might have stuck it out if Gra hadn't irresponsibly chosen to go and feed and clothe and raise a child - and with a US label now putting loads of support behind them bcz Reznor asked, they prob would have been a continuing success - but it all worked out pretty well for the dude with writer's block in the end.

I thought it was more normal to have solo albums that don't cause a split?

doesn't the My Morning Jacket guy have a bunch of solo albums?

the Parquet Courts guys too

Animal Collective

Big Thief. (I read that sometimes Adrianne will do a solo set at a Big Thief show, and the other guys will set down their instruments and watch.)

course if it's true there was a racist showing their ass in the front row, pretty weak if nobody defended the dude from it

(xp - wtf)

Guitarist Buck Meek also released a solo album in 2018; and somehow has time to fit in a touring side thing, despite belonging to a constantly touring "main band"(!)
