Agitation Free don't possess the hipster cache of Can, Faust and Amon Duul II, yet they created some of Krautrock's best music. The band's relative obscurity can in part be attributed to their idiosyncratic evolution. Unlike their peers, many of which turned more alien-sounding with each release, Agitation Free did the exact opposite. Thus, 2nd is far more rooted in American improv-rock circa 1970 than its predecessor, the insanely exotic Malesch. Nevertheless, this record is awesome; in a perfect world it would be considered a jam-band essential, right up there with Live/Dead and Eat a Peach.
