That’s a ridiculous question since the British Invasion (and Bob Dylan lyrically) essentially invented Rock music. Buddy Holly could have created his own genre of music or moved into another genre all together like Folk or Country (like Ray Charles, Jerry Lee Lewis, Wanda Jackson, Bobby Darrin, Dion, not to mention his bandmate Waylon Jennings). Speaking of Jennings, he was just one of the many young artists whose early records were produced by Buddy Holly who (with “the Cricket Sound”) could very well have rivaled Phil Spector or Brian Wilson as the most influential producer of the 1960s. He launched his own record label a full ten years before the Beatles did.
