Wasn't most, if not all of Smile released with the Beach Boys box set?
I think its only parts of Smile. hmm
Amazon.com essential recording
From "Surfin'" to "Kokomo," the first four discs of this box chart the Beach Boys' inimitable 30-year course. Here are all the hits and key album tracks, and an assortment of unreleased material that illuminates Brian Wilson and company's immense contribution to the development of pop music. (Especially fascinating are the assembled fragments from Wilson's abandoned 1966 masterwork, Smile.) A fifth disc features demos, radio spots, live tracks, and studio goodies for the hardcore fan. The set confirms Brian's hardworking genius, but also gives each member his due, especially the late Carl Wilson. Rock & roll music grew up with the Beach Boys, and this box is rock's best family album. --Ben Edmonds
