Kaplan announced that he had a “pretty serious health scare earlier this month” in a post on the indie rock band’s website Saturday. The musician left out any details about the ailment, noting that he was “going to be a little vague here” and that he wasn’t going to answer any questions about what happened to him.

“I’m well on the way to recovery, but I’ve not yet been deemed ready to Rock,” Kaplan wrote. “The good news is that I’ve been deemed ready to sit in a chair and play the concerts that mean more to me, Georgia and James than most anything else we do together. Our sets will undoubtedly be tweaked accordingly. In other words, if you were hoping to be in attendance for our annual airing of ‘Mushroom Cloud of Hiss,’ I’m afraid that is now zooming up the Unlikely chart with a bullet. But we’re confident that it’s going to be a great eight days.”

The sold-out “8 Nights of Hanukkah with Yo La Tengo” take place in the band’s hometown of Hoboken, N.J., at Maxwell’s Dec. 20-27. The shows will feature musical and comedic special guests that won’t be announced “until the last possible moment.” Proceeds will be donated to various charities.
