This three song single would please any Jurassic 5 fan. “Improvise” is a basic up beat song where the four MC’s take turns on the mic, each delivering a short verse. “Concrete Schoolyard” is a more laid back track. It features a nice piano loop and with some simple yet effective drums. “Concrete and Clay” is kind of a remix of “Concrete Schoolyard.” It features new lyrics and a new beat (another nice piano loop drum combination) but has the same chorus as “Concrete Schoolyard.” – Dan Gizzi
