I HIGHLY reccomend playing for him DESTINY UNBOUND from Superball, and CHALKDUST PRELUDE, a song that was only played twice as a way to introduce their song Chalkdust Torture. The most notable version is from July 11th, 2000 from a venue in Ohio I believe.
These two songs in combination with the STUDIO VERSION OF AXILLA II (NOT AXILLA!!!) should help in understanding why Phish is worth respecting and keeping in one's mind as good group of musicians
