Definition: A band you might have once considered your favourite or loved once that now you can’t handle their new stuff, and it has tainted their earlier work.
For me the one that springs to mind is Muse. I imagine this’ll be the one for most folk here. I adored their debut and the follow-up were quite literally life changing at the time. It is hard to believe, but once Muse were one of the most interesting “rock” bands in the UK. I gobbled up Absolution like it was crack-covered Coco Pops and then when Blackholes and Revelations came out I convinced my self it was pretty incredible, but it feels oddly anaemic now.
I, like a few here, used to post on the Muse message board back in the day.
Obviously, nowadays they’ve entered the realms of self-parody and impossible to love mode. Can barely listen to half their earliest stuff now.
