I think even Dark Side of the Moon got off to slow start in the US.
It did hit #1 for 1 week almost 2 months after it came out. Then lost out to Elvis’ Aloha From Hawaii. World is a Ghetto by War is actually the #1 album of 1973, which honestly is better than most years’ #1. But still trash when you remember that’s the year of Dark Side, Houses of the Holy, Quadrophenia and Goodbye Yellow Brick Road.
