Mine for the longest time was Disc Three, except for Gettin Jiggy With It (although I am not a huge fan of the “Fish songs”).
However, lately my favorite has been one I am sure many people may disagree with me about, Disc Two. I love the way the disc flows, starting off with Mike, than raging with Possum, slowing down with Roggae and Driver (which is climbing my ladder of favorite lyrical Phish songs), and ending with a ripping Melt.
I think out of all the discs, this may be the best played all around, even though the song list may not jump out as amazing.
