So what are the possibilities this year?

The Times' Lewis is feeling, "Layla," Eric Clapton's record with Derek and the Dominos, or possibly The Jimi Hendrix Experience's "Are You Experienced" or "Led Zeppelin IV."

Phish.net has a post by David Zzyzx Steinberg on the "Halloween Rumor Mill" in which he makes the case for and against Genesis' "The Lamb Lies Down on Broadway/Selling England by the Pound," Queen's "A Night at the Opera," King Crimson's "Lark Tongue in Aspic" and Paul Simon's "Graceland."

All Anastasio would say is that "this one's for me. The one we picked, I'm going to get more out of this as a musician than I ever have before.

"Three songs into it, I called everybody and told them, 'None of the other ones - I wouldn't think, hopefully - will have nearly the effect on my playing this one's going to.'"

However, the Halloween experience won't be just a fleeting memory for those who managed to score tickets to the sold out show.

Phish fans typically take matters into their own recording devices by making bootleg copies of the band's shows - no two of which are alike - and trading them.
