Not bad at all. Not exactly brilliant either, but this recorded free-form "freak-out" from 1967 (originally released on New York City's Audio Fidelity label) is not only not terrible, but surprisingly pretty OK for stretches, especially considering the typical quality of these types of had-to-be-there period curios that purport to blow your mind with an aural approximation of an acid trip. This one actually manages to be something approaching far out, man, even at its most half-baked. Whether How to Blow Your Mind and Have a Freakout Party was, in fact, created as a "head" LP by practicing heads (a certain David Dalton is listed as the Unfolding's presiding mastermind - no word in the liner notes if this is the same Dalton who was a pioneering rock scribe and founding editor of Rolling Stone), or as an exploitation of same by a faceless assemblage of session musicians is really anyone's guess…
