'"Send Them/Entropy (Hip Hop Reconstruction from the Ground Up)"', is a double A side EP by Asia Born (now known as Lyrics Born) and DJ Shadow and the Groove Robbers. This was released 1993 from Solesides. Parts of this were later featured on the retrospective album Solesides Greatest Bumps.

In thermodynamics, entropy (usual symbol S) is a measure of the number of specific realizations or microstates that may realize a thermodynamic system in a defined state specified by macroscopic variables. Entropy is commonly understood as a measure of molecular disorder within a macroscopic system. According to the second law of thermodynamics the entropy of an isolated system never decreases. Such a system spontaneously evolves towards thermodynamic equilibrium, the state with maximum entropy. Systems that are not isolated may decrease in entropy, provided they increase the entropy of their environment by at least that same amount. Since entropy is a state function, the change in the entropy of a system is the same for any process that goes from a given initial state to a given final state, whether the process is reversible or irreversible. However, irreversible processes increase the combined entropy of the system and its environment.
