Janet was actually on The Center Won't Hold but left the band almost immediately after they finished recording it. Like, they did one of the songs together on the Tonight Show, tickets went on sale for the tour the next morning, and then she announced she was gone by mid-afternoon. That was still enough time for me to immediately buy a ticket to the Seattle leg, though
(They were okay, the replacement drummer was talented, but it kind of felt like they were blitzing through playing the set as fast as possible. The title track for that album was pretty good live?)
But then yeah, the weirder part is that rather than continue down that path and try to make it work they've sort of just moved on to glossier-sounding indie rock.
