"Picture Of Nectar" is one of my faves.
"Rift" is good.
Well, Phish's first record was "JUNTA" and that features staples "You Enjoy Myself," "Divided Sky" and "Fluffhead" - that's what I heard for the first time back in '92 and that's still what I'd suggest today. A next favorite and far as amazing album composition from start to finish would be "RIFT" - after that album it was more a collection of songs instead of full album concept and flow.
