Some of the songs, like "That's All Right", were in what one Memphis journalist described as the "R&B idiom of negro field jazz"; others, like "Blue Moon of Kentucky", were "more in the country field", "but there was a curious blending of the two different musics in both".
Beberapa lagu, seperti "That's All Right", merupakan apa yang seorang jurnalis Memphis sebagai "idiom R&B dari jazz bidang negro"; yang lainnya, seperti "Blue Moon of Kentucky", "lebih ke bidang country", "namun terdapat percampuran dari dua musik berbeda pada keduanya".
