The above was posted five days before Bo Diddley's death, June 2, 2008. He was not just a giant of rock n roll, he was a major American artist - a consummate innovator who pushed the form to the edge of pure rhythmic sound. Among his most distinguished peers, he was the avant garde -- his contribution is absolutely unique.
