Just after Christmas, musician Erika Stahl from the local Americana duo Muddy Ruckus had to undergo emergency dialysis and spent four days in the hospital. Her battle with polycystic kidney disease that started when she was 14 years old took a dire turn, and thousands of dollars of medical bills have piled up. She is currently undergoing dialysis three times a week for several hours at a time, leaving her unable to work. The local music community is stepping up to help. All proceeds from this show will go directly to Stahl, and you’ll get to see performances from Mallett Brothers Band, Five of The Eyes, The Youngerbloods, Jenny Lou Drew Band and Max Garcia Conover.
