I've lost count of the number of bands where it went a bit pear-shaped after the first album (or maybe the first two).
and for some it's beyond their control. Maggie thatcher managed to kill thrashing doves' career overnight by admiring their video for the single beautiful imbalance on a Saturday-morning kids programme. (https://www.theguardian.com/music/2004/ ... atives2004)
though, realistically, though their first album was a breakout, their second album was pants. I got the impression the label wanted them to be more inxs. and they obliged. but not in a good way. one of them later wound up part-timing for death in vegas.
