Yesterday Greg Lake succumbed to cancer. A founding member of King Crimson and Emerson, Lake, and Palmer, he evolved into an elder statesman of progressive rock. This genre has stood the test of time. Trained in classical music and and more modern genres, Lake and his peers combined the best parts of them.
"Lucky Man" was used as filler for an ELP album but has become much more than that. I referenced it in my recent poetry class when discussing the 17th Century Cavalier poets.
We were lucky to have had Lake with us, and lucky still to have his immortal music.
