What I know of it is what was posted by Full Tilt Ice Cream on the Facebook:
This Thursday at White Center we are starting a monthly folk/bluegrass series hosted by Squirrel Butter and the Lipid Lickers. Squirel Butter is mostly memebers of the the famed Tall Boys bluegrass band.
Thursday April 22nd
Old-Time Ice Cream Social w/Squirrel Butter & the Lipid Lickers
open Old-time Jam to follow
Full-Tilt Ice Cream in White Center
7:30-10PM - All ages!
(Should you want to eat some actual food before ice cream and beer at show I can personally recommend the Triangle Tavern (9454 16th Ave SW) a decent slightly divey joint for good bar burgers and Proletariat Pizza (9622-A 16th Avenue Southwest) right across the street from Full Tilt.)
