The beauty of the Concord Music Group's treasure trove of a catalog is that it will always provide material for the "Reassessing" column at All About Jazz and similar columns elsewhere. The newest round of re-releases celebrate the 60th anniversary of Riverside Records. Riverside Records was founded by Orrin Keepnews and Bill Grauer in 1953, remaining a major force in jazz recording in New York City for a decade, when Grauer perished from a heart attack and the label declared bankruptcy. The catalog was acquired by Fantasy Records in 1972 and the catalog released under the Original Jazz Classics imprint. Concord Records purchased Fantasy Records in 2004, creating the largest jazz catalog available.
