Why are Elvis Presley sun recordings considered to be more important than his rca recordings?

Elvis Presley's Sun recordings are often regarded as more important because they represent his raw, pioneering sound that helped to define rock and roll. These early tracks, produced by Sam Phillips, capture the innovative blend of country, blues, and rockabilly that showcased Elvis's unique style and vocal talent. Additionally, the Sun label recordings marked the beginning of his career and his emergence as a cultural icon, while his RCA recordings, although commercially successful, were often more polished and less groundbreaking. This raw authenticity resonates strongly with fans and historians alike.
