101 cuts from the most important post-WWII blues label, including 19 unreleased recordings and over two dozen singles making their album debuts (which means those with every Chess re-issue only own about half this set!). All the big names-Muddy, Howlin' Wolf, Sonny Boy, Little Walter, Willie Dixon, John Lee Hooker-are here, along with a 64-page book with track-by-track credits and rare pix. Superb.
