Chris Cornell's final music video, filmed before the singer died in May, was released Tuesday. The video for "The Promise" was released to coincide with World Refugee Day, the AP reports. Eric Esrailian, who produced the video, said Cornell filmed the video in Brooklyn shortly before he died at age 52. Esrailian added that the Soundgarden and Audioslave frontman wanted the video to be released on World Refugee Day. Cornell and his family toured refugee camps in Greece in April, and there they decided that the Chris and Vicky Cornell Foundation would focus its efforts on child refugees.
