I personally think Jambi should be essential listening for all bass players who use effects that would be considered too "out there" for most players. It's like a Phd level course in how to carve out space in music so these effects like delay and flanging can be heard and more importantly discerned. Very deep tones in that song, besides being an amazing piece of music. I saw Tool on the 10,000 days tour, but before the arena shows. They were doing a run of small theaters. Saw them here in NYC and it was intense. Can't remember if they played Jambi or not though.
