Super fun song. Simple and great. The gospel/blues riffing is just enjoyable all around. Phish is fantastic. They can play loads of different genres, all within one single show. So, it can be a little divisive...
The album "Rift" is one of the tightest, mindblowingest albums ever. People don't give them enough credit for their studio stuff. I recommend "It's Ice"
Glad you enjoyed Julius. Just as a side: A lot of their albums, such as Hoist, are meant to be heard from start to finish. And of course, seeing the band live will blow you away. Hoist, Rift and Billy Breathes are three of Phish's greatest albums IMO but there is sooooo much to listen to. If you like what you heard here, I would recommend just taking a break and listening to this album in it's full length. You seem to appreciate all types of music, so I can guarantee it will not disappoint. Check out some of their live performances on RU-vid as well!
Phish is really a prog rock band disguised a jam band (especially with their older stuff). They were hugely influenced by Zappa, Yes as well as Talking Heads, Bowie, Velvet Underground, etc.
The song features backing vocals by Rose Stone, Jean McClain and the Rickey Grundy Chorale and horn instruments by the Tower of Power Horn Section. Go to a show and experience the bliss for yourself! It cannot be described.
This song is all about Julius Caesar. The Aquitani were a tribe in the Pyrenees. And Caesar was involved. Here's the link en.wikipedia.org/wiki/Aquitani
