Pitchfork reports that the cryptic one has injured his Skelethon about the rib, and will not be able to make the West Coast dates on his current tour. He was scheduled to perform in Seattle on the 25th. He's released a short statement on the Rhymesayers site:
Hey all - I broke a fucking rib like an asshole. After consulting with my doctor it was recommended that I wait a few more weeks before being on stage and postpone our January dates. The entire scenario sucks and I realize how aggravating this is for everyone involved - I am sorry this has happened! 2013 promises to be plentiful, and I look forward to getting on with the shenanigans as soon as possible.
Would-be venue Neumos tells us "WE WILL BE RESCHEDULING & ALL PREVIOUSLY PURCHASED TICKETS WILL BE HONORED. NEW DATE TO BE ANNOUNCED SHORTLY."
Here are some cool Aesop Rock videos to soften the blow:
