I'm amazed no one's mentioned 'The Wilson Family', their powerfull harmony performances have been a high spot for me at Whitby folk week in recent years. Some 'Swan arcade' material has recently been reissued, their version of 'The Kinks' 'Lola' is wonderfull. My most spine tingling harmony moment however was seeing a Bulgarian womens choir in Norwich Cathedral about ten years ago, the recordings I've heard don't match up to that live performance - incredible acoustics enhancing theunearthly harmonies. -- Phil
