GRP Records, known as the “Digital Master Company,” celebrated its 30th anniversary as an independent label with the release of “GRP 30,” a compilation of contemporary jazz covering the past three decades. Legendary bass player Charles Mingus was remembered with a new seven-disc collection called “The Jazz Workshop Concerts, 1964-1965.” And, renowned crooner Tony Bennett, performing alongside Aretha Franklin, Willie Nelson, Amy Winehouse, Michael Buble, and more than a dozen other stars, reached the Number One spot on the Billboard 200 Albums chart for the first time ever with his top-selling album, Duets II.
