So yesterday proved to be a day wracked with tragedy for the music world, as it was announced in the early evening that singer Teddy Pendergrass had died after a months-long battle with colon cancer. He was one of the most successful R&B singers of the 1970s, first with Harold Melvin and the Blue Notes, with whom he recorded "If You Don't Know Me By Now," and then as a solo artist whose biggest hits included "Close the Door" and "The More I Get the More I Want." Pendergrass was known for his strong, booming baritone, which he used to usher in a new era of sexually charged R&B that's still echoed today. After a 1982 car accident that would confine him to a wheelchair for the second half of his life, hecontinued to record, but focused much of his energy on helping others with spinal cord injuries. Pendergrass died in a hospital in suburban Philadelphia. He was 59. After the jump, a few videos.
