The winter solstice is going to get jammy at the Fox Theatre.

Hot Soup and Dead/Phish Orchestra are playing a Winter Solstice Party at the Fox on Dec. 21 (of course). Expect that familiar mix of funk, rock, fusion, jazz, reggae and blues from Boulder five-piece Hot Soup and high-energy takes on Phish and the Grateful Dead from the Dead/Phish Orchestra.

Tickets go on sale Friday, Nov. 9, for $8.
