The Fishstock concert series at Camp David Party Barn in Door County begins its 21st season in July. The series brings acclaimed folk and bluegrass musicians from around the country to perform in the 100-year old dairy barn. This year's lineup includes returning favorites like Eric Lewis, Chris Irwin, and Karen Mal, as well as some new acts like jazz artist Janet Planet and the acoustic swing duo Mal-O-Dua. The concerts have been running since the 1990s and help introduce genres like bluegrass to Door County audiences in an unconventional rural setting. The all-volunteer organizers struggle to compete with other free local concerts but hope advance online ticket sales will help the series survive into the future.
