"... Radical Action is the definitive live Crimson release from the definitive live Crimson lineup; more than enough to bolster the suggestion that Fripp is, indeed, the Miles Davis of the progressive/art rock world...and, considering the full breadth of his career, other arenas as well. And for that reason alone (and there are many others), Radical Action (To Unseat The Hold of Monkey Mind) is a landmark recording from a group whose discography is filled with them".
