Castle Rock Summer Jam was started by local musicians Bill Clarke and John Saunders in 2017. The purpose of Castle Rock Summer Jam is to provide an opportunity to enjoy an all-day music festival close to home, complete with local Food and Beer vendors, while making a positive impact in the community. A portion of the proceeds from 2018 jam will benefit the Douglas Elbert Task Force. A number of Castle Rock Summer Jam scholarships will also be created in 2018 to benefit local High School students who participate in music programs. The lineup will include Johnny Richards, Sarah P and the Dirty Logger, The John Saunders Band, Solar, and Big Head Todd!
