24 track compilation contains the best & virtually all of the recordings that this brother/sister duo made for Musicor's highly collectable Dynamo subsidiary. Recorded between 1966 & 1968, it followed their successful period at Sue Records, where "Mockingbird" scored a #2 R&B hit. This is the only CD compilation of their Dynamo recordings available, and it also includes a superb later version of "Mockingbird" with strings.
