In case the 32 tracks of obscure, 1950s rockabilly offered on the first volume of this series weren't enough for you, here are 30 more. (And if you still want more, the series continues for another three volumes). For those with a passing interest in the music itself, just the immensity of the archeological accomplishment represented by this series is enough to make the jaw drop. But for those with a deep love for this period of American musical history, these discs are a treasure trove. Obviously, not everything on offer here is a gem, and every one of the five densely packed anthologies in this series could have been reduced by about one-third without any regrettable loss of content. But the diamonds are all the more thrilling for the effort it takes to find them: "Red Hot Mama" by Wayne Williams & the Sure Shots is one such, as is the swinging "Enie Meanie Minie Moe" by Hoyt Johnson & the Four Recorders. On the other hand, the Braves' "Woodpecker Rock" is stupid even by rockabilly's relatively relaxed intellectual standards, and the paleosexism of Gene Norman & the Rocking Rockets' "Snaggletooth Ann" will be startling to most modern ears. Like the others in the series, Rockabilly Rarities, Vol. 2 is more than just a historical document, but it probably won't convert anyone who needs to be converted.
