Query: Get the RVG

You really can't go wrong with any of the Art Blakey & The Jazz Messengers titles with Wayne Shorter (1959-1964), and The Big Beat is no exception, but there's a reason why there aren't any new versions available of this particular edition. Get the RVG version, which has far better sound, since it was digitally remastered by Rudy Van Gelder.
