Karoondinha Music & Arts Festival was a music festival which was to be held at Penn's Cave & Wildlife Park in Centre Hall, Pennsylvania.  The festival was officially announced on December 9, 2016.  The inaugural festival's full lineup was unveiled May 2, 2017, and featured Chance the Rapper, John Legend, ODESZA, Paramore, and Sturgill Simpson as headliners.  On June 27, 2017 the festival's official website and social media went dark signaling the festival had been cancelled.  Compounded with the festival's reported financial struggles, an overarching factor in the closing of the festival was a result of the May 22nd terrorist attack of an Ariana Grande concert in London.  Many consumers feared the possibility of a similar attack taking place at the venue in Penn's Cave, forcing ticket sales to plummet, and subsequently, contributing to the cancellation of the festival. A Christian music festival (also known as a Jesus music festival or simply a Jesus festival) is a music festival held by the Christian community, in support of performers of Christian music.  The festivals are characterized by more than just music; many feature motivational speakers and evangelists, and include seminars on Christian spiritual and missions topics, service, and evangelism.  They are often viewed as evangelical tools, and small festivals can draw 10 times the crowd of traditional revival meetings.  While the central theme of a Christian festival is Jesus Christ, the core appeal of a Christian music festival remains the artists and their music.  Critics point out that the dichotomy of business and religious interests can be problematic for Christian festivals.  In similar ways as the Christian music industry in general, festivals can be drawn away from their central theme and gravitate toward commercialization and mainstream acts in an attempt to draw crowds.
