With this “beats and loops” collection, Public Enemy became the first major hip-hop act to release such a collection. The collection includes over two hours of “beats and loops,” presented in a “construction kit” format (fully mixed loops and all of the individual samples used to make up the entire loop).

“What’s most important here are the samples themselves. So are they any good? Well, the content of the kits is, in a word, excellent. Style-wise the kits are quite unique, rather than emulating any trends. And the sound quality is top notch, as is the selection of samples and elements. All the drum loops
have the required beef and bite and contain a mixture of played and programmed beats that works well. The rhythms themselves range in style from the standard ‘boom-bap’ to more complex patterns giving a varied palette of loops to choose from. 5/5.” (Sound On Sound)
