Despite the relatively poor quality sound, the recording leaves you in doubt as to the charisma and impact of Elvis. Album opener Blue Suede Shoes would remain his calling card- thumping, energetic bluesy rock sung by a man in a hurry. His versions of old classics, delivered in an almost offhand manner with curled lip just adds to the cool appeal - no wonder the old crooners were terrified. Popular music would never be the same again.
