Bad news for fans: Yonder Mountain String Band just announced that it was postponing all of its shows from February 11 to 15, with the vague explanation, "due to circumstances surrounding the band." That includes this Friday's previously scheduled gig at Revolution.
The okay news is that rather than an outright cancellation, the show will, indeed, be rescheduled. Stay tuned to Crossfade for details, and for information on refunds/using tickets for that later date.
