Soul on the Rocks is the fifth studio album by the Isley Brothers. It was released on the Tamla (Motown) label on August 29, 1967. Their second and final album with the Detroit label, the brothers soon felt disenchanted with their stay at Motown while established groups like the Temptations and the Four Tops, whose styles were more polished than the Isleys, got more promotion. One of the album's tracks, "Behind a Painted Smile" found chart success and made them popular in the United Kingdom, as the Isleys found out on a tour of the country during this period. Motivated, they eventually left Motown and re-formed their T-Neck record label.
