I don’t think Phish sounds much like the Dead (though someone who never listens to jam bands might disagree), but “Roggae” has a significant “Birdsong” vibe. For the most part, however, the band that Phish really sounds like is … Phish. They’re still playing the same damn song they were playing five minutes ago – when I had noticed that wow, they’re still playing the same damn song they were playing ten minutes ago!”
