On Grassroots, 311 experiment even more than on Music. It isn't as here-we-are-world-f**k-the-bullsh*t-it's-time-to-throw-down. Music certainly has its mellow points but Grassroots spans the spectrum of emotional expression more thoroughly. The self-titled blue album focused more on the "heavy groove" side of 311. Grassroots falls nicely between their varying styles.
