The O'Kanes produced three albums of absolutely superb country music. The self-titled, first, and arguably strongest effort contains everything that is best about the O'Kanes' sound. It is rich in country music's finest traditions, yet it is by no means a nostalgia album. It is sparse in instrumentation, yet richly textured. Most of all, the album contains direct, honest music whose emotional intensity stays with the listener long after the sound waves have stopped vibrating. The O'Kanes' vocals recall the best of country harmony. Some critics liken them to the Louvin Brothers. Others, because of the more driving sound of their backing, compare them to the Everlys. The instrumental sound ranges from bluegrass (prominent mandolin) to the tense drive of Sun rockabilly (their hit "O Darlin'" is evidence of this). The addition of an accordion adds both Tex-Mex and unmistakably bluesy feels to the proceedings.

Following the recording of their third album, Kane and O'Hara parted ways in 1989; the third record, Imagine That, was released posthumously to little attention in 1990. Following the group's breakup, both members continued to work as professional songwriters. In 1993, Kane released his eponymous solo debut on Atlantic Records; O'Hara released his first solo album, Rise Above It, the following year on RCA.
