Edison will release the "Lion's Heart" EP at the end of this month. It's the first release from the Denver band since releasing its debut full-length in 2016. It's also the trio's final record, as Edison will split up following a farewell tour this fall. Edison stopped into the CPR Performance Studio for one last OpenAir Sessions performance. The band members played some new music and spoke with Bruce Trujillo about the decision to end Edison, writing the EP during a residency at Fort Collins' Music District and highlights from their last three years on the road.
