Wikipedia Background
To Our Children's Children's Children is the fifth album by The Moody Blues, first issued in late 1969. It was the first album released on the group's newly formed Threshold Records label, which was named after the band's previous album from the same year, On the Threshold of a Dream.
It was inspired by the 1969 moon landing, and the songs centre around the twin themes of space travel and children, with minor-key tonalities and a distinct psychedelic influence.
It is the fourth of what are popularly considered the group's "core seven" (or Classic Seven) albums from 1967 to 1972, and as such represents the peak of their career to some.
The band found most of the songs impossible to perform live, due to extremely lush orchestrations and a great deal of overdubbing. For this reason their following album, A Question of Balance, was more stripped down and basic in instrumentation. This change only lasted for one album and the next, Every Good Boy Deserves Favour, saw a return to their earlier orchestral sound.
