This year is the 80th anniversary of Blue Note Records, the venerable jazz label established by Alfred Lion and Max Margulis in 1939. While other record companies played important roles in documenting jazz, Blue Note’s presence in the marketplace overshadows them. It’s doubtful that any other jazz label is better known, or has more recordings currently available in various formats -- the number of Blue Note titles in circulation on CD, as downloads, or on recent vinyl pressings is staggering. Blue Note is also a favorite of audiophile reissue labels, several of which have licensed albums from its catalog to release as new LPs.
