Welcome to the 290th edition of Phish.Net's Mystery Jam Monday, the first* and easiest of September. The winner will receive an MP3 download code courtesy of our friends at LivePhish.com / Nugs.Net. To win, be the first person to identify the song and date of the mystery clip. Each person gets one guess to start – if no one guesses correctly, I will post a hint on Tuesday, after which each person gets one more guess before I reveal the correct answer on Wednesday around 10 AM PT / 1 PM ET. Good luck!

*Reminder: For the first MJM of each month, only folks who have never won an MJM are allowed to answer before the hint. If you have never won an MJM, please answer as a blog comment below. If you have previously won an MJM, but you'd like to submit a guess before the hint, you may do so by PMing me; once the hint has been posted, everyone should answer on the blog. If that's confusing to you, check out the handy decision tree I threw together to help guide you. If you're not sure if you've won before, check in the MJM Results spreadsheet linked below.

Answer: Come stumble MJM beatin' worker, our winner is @JezmundBezerker [sic], who made short labor of this holiday mystery jam for his first W: 9/2/12 "Sand" from Dick's 2012, five years ago this week (already?). Watch this classic rendition in HD here, now, if you don't remember its glory – and drop by on Monday if you're up for a challenge: we'll get two clips for the first time in a while.
