This compilation, released concurrently with Greatest Hits, collects some of the band's stranger experiments, early album tracks, and a few rarities, such as the Booji Boy releases of "Be Stiff" and "Mechanical Man" (both available on the Hardcore compilations) and a U.K. B-side, "Penetration in the Centerfold." It does serve as a good supplement to the Greatest Hits collection, even if it is a bit haphazard, but listeners who want more than one Devo disc are advised to go ahead and purchase the first three albums rather than these two compilations -- it's a better way to appreciate their achievements, and it's more entertaining. ~ Steve Huey, All Music Guide
