Rockabilly collectors are a hearty, fanatical breed with little compunction about seeking out rare, rarely heard singles based on legend or label. Not everybody has the time or patience to find original pressings, even if they love the music, so for the average collector, Bear Family's multi-volume That'll Flat Git It! series is the way to dig deep into the rockabilly arcana. The series is divided by label, spotlighting the forgotten sides and smaller hits for labels as well-known as Decca and RCA, along with lesser-known regional labels. This is not everything that was released on a label, of course, but it is a fairly thorough overview of what kinds of rockabilly the label released, and it hits almost all of the high points, at least as far as rockabilly collectors are concerned (and when the label can't fit everything on one disc, it breaks it up in two parts). Like many multi-part series, this is strongest on the earlier volumes, but if you're a dyed-in-the-wool collector, any of these volumes are worthwhile. Some of them are loaded with generic mediocrities, but they all have a couple of dynamite gems, plus they're presented lovingly, with wonderful sound and detailed, well-researched liner notes. This is essentially a collector's series, but it's a collector's series in the best sense — filled with rare gems worth seeking out and presented in a luxurious fashion.
