Hepcat found this on Boing Boing.  Dinosaur Jr. played at Warsaw in Williamburg on August 29th.

Dinosaur, Jr’s entire collection of gear has been stolen out of their
trailer, and they’re trying to recover it before they have to start
cancelling gigs.

After a blistering set last night in Brooklyn, NY the band awoke this morning to find that the their trailer had been broken into and all of the gear has been taken.

J’s Amma guitar, the mountain man guitar, Lou’s Rickenbacker… EVERYTHING IS GONE. They are still taking inventory to see what else is gone but they were pretty much wiped out.

WE NEED YOUR HELP!!! Spread the word to everyone you know, every music store, pawn shop, club… anywhere you can think they may show up.

If you have ANY information let us know – management@jmascis.com.
