This has not been announced on the Higher Ground website, but according to an article in the Burlington Free Press here, Page McConnell and Jon Fishman will join other Vermont musicians including Russ Lawton and Ray Paczkowski (both of whom play with TAB), Bob Wagner, Joshua Panda, Jer Coons and others for a benefit performance at the South Burlington nightspot on Februrary 3rd. The show will benefit Pete's Greens, a northern Vermont organic farm which suffered a fire last month.
More details will be available on Brent Hallenbeck's blog, Brent's Notebook, on the Free Press site which broke the story, as well as the Higher Ground website.
Tickets are expected to go on sale at 11 am tomorrow, Friday, January 28.
UPDATE: Tickets are not on sale yet, but a "bookmarkable" ticketing page is up on Higher Ground's website for the February 3 benefit event here.
UPDATE 2: Thanks to @johnnyd and @joechip for correcting earlier mistakes in this posting!
