Question

One aspect of buddy holly’s sound contributed heavily to his "crossover" appeal to diverse audiences

Answer 1

Odd as it might appear to be, a huge number audience members accepted that BH and the Crickets were a dark R&B gathering. His genuine name is Charles Hardin Holley. 
His style was impacted by gospel music, blue grass music, and musicality and blues acts, and he performed in Lubbock with his companions from secondary school. He showed up on nearby TV in 1952, and the next year he framed the gathering "Pal and Bob" with his companion Bob Montgomery.
