If many of these are true, there’s a good chance you’ll like Phish:

You love music, you listen to a lot of music, and you feel noticeably happy and energized whenever you get into a new album or band.

You love musical complexity, and you’re not crazy about the lack of it in today’s pop music.

You consider most modern pop music “overproduced”.

You don’t easily tire of the songs you love and hear often.

You’re a sucker for a good electric-guitar solo. Your favorite part of one of your favorite rock songs is the quick little guitar riff toward the end, and you wish it was longer.

You prefer to buy and listen to full albums rather than singles. (Bonus points if you rarely use shuffle, preferring to listen to songs in album order.)

You need a lot of music to fill long periods, such as listening in headphones while working at a computer all day."
