An old LP on the Coxone label from 1967 found at a flea market some time ago. Its a bit scratched so please forgive the blips and pops.
"The Soul Vendors the group that gave us 'Rock Steady', the phrase originated by Coxone Dodd, the record producer and owner of Studio One studio. This new sound was much slower than Ska, stronger base line and a persistent shuffling rhythm together with some very fine sax and trumpet solo's, and the organ was used to greater effect. The vocal styles were very soulful, heavily influenced by the USA soul and R & B records of that period. "Rock Steady" by Alton Ellis issued in 1967 on the Treasure Isle label sums up the new style, using repeat upbeat guitar riff and the brass section answering the vocals, beautiful sax solo, even a vocal backing group, all added up to a suberb production by Duke Reid who went on to make this new sound his own.
