Special Christmas. The music video for "Christmas in Hollis" was shot in Hollis, Queens. Run-D.M.C. filmed the video during their 1987 tour. DMC's mother made a guest appearance in the video. In 1997, McDaniels began to develop a deep depression. He became extremely unhappy with the rigorous routine of touring and performing, and with being away from his wife and newborn son. He began to rely heavily on prescription drugs and alcohol to ease the pain. While on tour, McDaniels noticed his voice was giving out. He was later diagnosed with spasmodic dysphonia, a vocal disorder which causes involuntary spasms of the larynx muscles. He believes it was caused by the aggressive way in which he performs his lyrics compounded with the years of heavy drinking. Meanwhile, McDaniels began to have creative differences with his bandmates in Run-D.M.C., which by then, was well past its prime as a commercially successful hip-hop group. A longtime fan of artists such as The Beatles, Bob Dylan, and Harry Chapin, McDaniels wanted to move towards a slower, softer sound which suited his now troubled voice. Run wanted to continue with the aggressive, hard rock-edged, sound that the group was known for. These disagreements caused McDaniels to sit out most of the recording of Crown Royal (2001). He appeared on only three songs. Feeling depressed and suicidal, McDaniels heard fellow adoptee Sarah McLachlan's song "Angel" (1997) on the radio. The song touched McDaniels so deeply that it inspired him to reassess his life and career. He credits McLachlan and her album Surfacing (on which "Angel" appeared) with saving his life. With a new outlook on life, McDaniels decided to write his autobiography. While researching his early years, his mother, Bannah, revealed a shocking secret: Darryl had been placed for adoption when he was three months old. According to Bannah, his birth mother was a woman of Dominican descent named Bernada Lovelace. He also learned that he was born in Harlem, Manhattan, not Hollis, Queens, as he had always believed. Even as a child, McDaniels knew he did not look like the rest of his family, and with the revelation, he finally understood why. The news inspired him to search for his birth mother. He began working with the VH1 network on a documentary chronicling his quest. His autobiography, King of Rock: Respect, Responsibility, and My Life with Run-DMC, was released in January 2001.
