Roar (song) is on the 2017 album Prism.
 Graham Nash of The Hollies described his experience in developing a solo album as follows: "The thing that I go through that results in a solo album is an interesting process of collecting songs that can't be done, for whatever reason, by a lot of people"
The album was the dominant form of recorded music expression and consumption from the mid-1960s to the early 21st century, a period known as the album era
