"Sam Phillips originally drafted Elvis to replace an absent ballad singer but, after pairing him with ambitious guitarist Scotty Moore and his upright bass-playing friend Bill Black, the music quickly veered in another direction entirely; the SUN Sessions began as an impromptu jam, the absence of drums being purely incidental given it was a small studio, but the light echo the producer used to compensate, inadvertently had an effect on Presley's own voice which was far more interesting; Elvis himself was a raw talent, but his singing prowess was immediately apparent, with a vocal range of roughly three octaves, perfect control and ability to jump between bass, baritone and tenor with the greatest of ease; over fifty years after the fact, we can see that what teenagers saw in him, was a genuinely brilliant vocalist that could just as easily convey a soft ballad, as it could a wild rock song; as a rule, the importance of an album is completely separate from its actual quality but, invariably, albums this influential are influential because they're genuinely great recordings, and "The Sun Sessions", though not formally compiled until 1976, were certainly great, great classic recordings."
