Few 1950s rockabilly platters more rousingly define the genre -- or more fully capture its decadently dangerous side -- better than Elvis Presley's February 5, 1955, Sun Records waxing of "Baby Let's Play House." Produced by the legendary Sam Phillips at his fabled studio at 706 Union in Memphis, the incendiary performance hails from rockabilly's formative era, when the rules hadn't yet been cast in stone and Elvis was still experimenting in overdrive, searching for the compelling sound that would catapult him to icon status in little over a year (the track proved Presley's first national hit, rising to number five on Billboard's country charts midway through 1955). Presley's slapback echo-laden hiccuping-briefly rendered a cappella before the snarling low-end guitar of Scotty Moore enters, crackling with roadhouse-tested fire segues into an irresistibly lascivious declaration of lust and (at least on the final payoff line) a not-so-subtle hint of violence. Both of Moore's immaculately conceived and executed solos were monstrously influential to the rockabilly idiom, copied by countless Southern axe-wielding teens, and Bill Black slaps his thundering upright bass so percussively that no drummer was necessary. Like Elvis' 1954 remakes of Arthur "Big Boy" Crudup's "That's All Right" and Roy Brown's "Good Rockin' Tonight" that preceded it in Sun's catalog, the song was born as a blues. It was written and first cut by Nashville blues guitarist Arthur Gunter, whose less urgent reading was riding high on the R&B charts at that moment for Ernie Young's Excello label. Yet it was Elvis' glorious cover, loaded with rude, hormonally goosed exuberance and captured brilliantly by Phillips behind the board, that makes the track integral to Presley's musical development. Buddy Holly, Sleepy LaBeef, and many other lads who shared the rockabilly fever paid tribute with sound-alike versions (right down to nailing Moore's solos note for note), and the Johnny Burnette Trio's romping "Oh Baby Babe" was so similar that it might as well be credited as such.
