You can't mention rockabilly without mentioning Johnny Burnette, or more precisely, the Johnny Burnette Trio, since credit must go to the overall sound rather than just Johnny's vocals. The Trio brought a level of aggression to rockabilly that wasn't there to anything like the same degree in numbers from Presley and Perkins. This is particularly noticeable on tracks like "The Train kept a rollin'" and "Honey Hush" where the rhythm pattern provided by Paul Burlison's guitar perfectly complements Burnette's vocal delivery, full of hiccuppy effects and with added shouts (presumably by Dorsey or Paul). The original of Honey Hush from the great blues shouter Big Joe Turner was a fine performance in its own right but the Johnny and the Trio manage to cap it for excitement.
The boys had to go to US Coral in New York to get a recording contract since Sam Philips at Sun turned them down reportedly because Johnny sounded too much like a certain other singer he had! However the Trio's rockabilly tracks for Coral, and they're all here, are rightly regarded as classics. And that's the aforementioned pair plus "Tear it up", "Lonesome Train", "Eager Beaver baby" and more. In between we get country tracks sometimes, like "Sweet love on my mind", sprinkled with some rockabilly dust. On others there are some slight hints of the later brief pop career that Johnny (and Dorsey) would enjoy. But that was for the future. This was now and this was Johnny Burnette in his pomp and was how he would be recalled in the annals of rock history.
