I don't usually like keyboard metal, Joe South (who also wrote "I Never Promised You a Rose Garden") or Deep Purple. But thanks to Jon Lord, I enjoy "Hush."
Other than Ray Manzarek, I can't think of a major '60s rock organist who was so vital to his band. Lord's grasp of the rhythm here makes me wonder if he also played drums. His solo reminds me of the best guitar playing, where the space between the notes is just as important as actual notes. "Rick Wakeman, eat your heart out," Jello Biafra once said on Give Me Convenience or Give Me Death. Jon Lord beat him to it, and he didn't even need words.
For Jon Lord, 1941-2012.
