Reception
Thom Jurek of Allmusic praised the collaboration as "a wonder", praising the fact that "everyone participates in creating something fresh and new, without anybody getting in anybody else's way. The spirit of cooperation and the excitement of discovery here are both prescient. The result is neither rock nor jazz, but a free-form music that dispenses with formality and ego and goes for the heart of the thing itself." He concludes: "For nearly a half-hour, the listener gets to eavesdrop on the purest kind of music-making by those dedicated to nothing else than the pursuit of its creation."
