The Principle of Moments (1CD)

The Principle of Moments was Plant's second Top 10 album in the US and UK. It also gave him his first solo Top 40 hit with "Big Log". The most popular track on album-oriented rock radio in the US was "Other Arms", which reached number-one on the Billboard Top Tracks chart. Genesis' drummer Phil Collins played drums for six of the album's eight songs (as he did on Pictures at Eleven). On the other two tracks former Jethro Tull drummer Barriemore Barlow performed.

Like Plant's first solo album, Pictures at Eleven, the songs departed from the hard rock sound of Led Zeppelin. Following the strength of these albums, Plant launched a successful tour in 1983. Phil Collins was the drummer for Plant's band for the North American portion of the tour.

Pictures at Eleven was certified Platinum in the United States for sales of over 1 million.
