Still finding ways to mix rock and techno elements together in a post-electro (clash) world, the Berliners featured on Insane IV manage to keep much of their material surprisingly fresh. Though a few tracks do rely too heavily on hackneyed themes (anarchy, androgyny), standouts such as Grizzly's "Dich" and Planningtorock's "Local Foreigner" take the fun and mayhem of the previous compilations into truly experimental realms. And to tell you the truth, even the more clichéd tracks are fun, in a pure dancefloor kind of way. A good find for someone with no Adult. in their collection.
