Final answer:
Brian Epstein, The Beatles' manager, was rejected by Decca Records, leading to disappointment but ultimately not hindering their success in the early stages of rock and roll.
Step-by-step explanation:
Brian Epstein was indeed disappointed when a major record label rejected The Beatles before they became one of the most iconic bands in the birth of rock and roll. The label in question was Decca Records, which famously passed on signing The Beatles after their audition on January 1, 1962.
This initial setback didn't deter Epstein or the band, as they continued to pursue their music career and eventually signed with EMI's Parlophone label, under the guidance of producer George Martin. Their subsequent success played a significant role in the evolution of rock and roll, which is reflected in the music and lyrics of the era.
