The six-CD set, which can also be pre-ordered at Amazon, contains more than seven and a half hours of music, including many of their greatest hits and more than 60 previously unreleased recordings. These include demos, alternate takes and mixes, and performance footage. One disc of rarities, called 'From the Vaults,' was compiled specifically to appeal to the hardcore Beach Boys collector.

The 72-page book, which is designed to look like a high school yearbook (complete with handwritten inscriptions from the four surviving original members and Bruce Johnston), contains photos and replicas of classic artwork and memorabilia, including Brian Wilson's 1959 high-school essay titled 'My Philosophy.'
