"All My Love" is the sixth track on Led Zeppelin's In Through the Out Door released in 1979. The song was written in honor of Robert Plants son Karac, who died while Led Zeppelin was on tour in 1977. Love may be evil, painful, and sometimes the best thing that will ever happen to you. When someone we love leaves or dies it is often too much to take. In 1977 Robert Plants son Karac, passed away from an infection. Led Zeppelin was on tour in New Orleans. While Plant checked into the hotel he got a call from his wife telling him that their son was seriously ill. Soon after, he passed away. The news shocked Plant and he quickly retreated back home to England. He quit taking everything that same day. No drinks, no drugs, just time with his family. Plant wanted to leave the band and pursue a career in education. Bonham (drummer for Led Zeppelin) finally talked him out of it over time. Plant overcame his sadness and his lowest times to keep doing what he loved. He began to make music again. The loss of his son was hard for him, but he went on to help others and make music that would cheer them up. In honor of his son's death, he wrote the song "All My Love." The song talks about the light dimming. Some believe that this is in reference to his own personal light dimming due to the loss he endured.
