As there is so much talk about the Simple jam, it is worth mentioning that the audience recordings are a required listening as well. Particularly from mics that capture the heavy deep end. There's a monstrous bass bomb right in the middle of the jam that doesn't come through with the official recording-- at least not on the version available via YouTube (which I am assuming is the same recording as the LivePhish app). To me it is the epicenter of the jam. Placement should be right at 13:30. You can hear the crowd react, but no elephantine bomb. With the aud mic recordings the reverberation lasts for about ten seconds. Experiencing live, because you could feel it simultaneously with hearing it, the end effect was as though it came from some place other than the band. A multidirectional quantum that emerged out of nowhere, warmly enfolded everyone in its presence and then faded back to the alternate plane where it had been summoned.
