What are some musical groups that you once thought were good but turned bad? Also what album or time period did they change?
For me...
Red Hot Chili Peppers. The Rick Rubin produced Blood Sugar Sex Magik was a turning point for me. Was not a fan of that album but it was okay. Everything after that was garbage as far as I am concerned. Everything before that when they all were on heroin was awesome.
U2 - everything that came after the 80s and when Bono started wearing those stupid glasses.
Genesis - everything that was made after Phil Collins solo work when he joined back up.
Beastie Boys - first two albums were amazing, then they decided to play instruments. That wasn’t a good choice in my opinion. Still get a kick out of Paul’s Boutique to this day.
Nas and Jay-Z - like so many rappers once they became filthy rich it’s like they lost their edge. Everyone likes rap songs about the struggle, everyone rolls their eyes when it comes to rap songs flaunting wealth.
