African Brothers Dance Band (International)

Perhaps Preslives can tell us more, but this seems to be a seminal 'Highlife' album. The band formed in the early 60's as teenagers and went through many transformations prior to this, their first LP. They were one of the first African bands to tour the U.S. and Canada in the same year (1970) that they did this album.
