The world's greatest R&B a cappella group hit their stride on this 1977 Elektra album, returning to the vocal-only arrangements that made them famous after some previous flirtations with instrumentation. The result was an album that many Persuasions fans consider their best, highlighted by Willie and Laura Mae Jones; It's Gonna Rain; Papa-Oom-Mow-Mow; Sixty Minute Man , and more.
