We just got word that Jakob Dylan canceled his Rocky Mountain Folks Fest appearance, but the good news is that John Darnielle of the Mountain Goats will be flying in for a rare solo set on Sunday, August 17. KT Tunstall, Missy Higgins, Stephen Kellogg, Amos Lee, Patty Griffin, Nanci Griffith and others will also be at the fest that runs from August 15-17 in Lyons. -- Jon Solomon
