Hi Alio! It's actually Shape Note singing rather than Shaped Note (but I doubt if you're going to be slaughtered over adding a d!).

If you want to listen to more of the recordings that Alan Lomax and his lovely assistant made then this CD will give you what you want " Southern Journey Vol.9: Harp of a Thousand Strings", part of the Rounder Records Alan Lomax collection and readily available over here (Amazon have it for sale at £12.99). There is also another CD devoted solely to Sacred Harp which I think may be Southern Journey Vol 10 (which I have been meaning to buy for a long time, but never quite got round to).. Both of these recordings give you the real deal - very raw, and not always musically accurate singing but thrilling and exciting stuff.

Other recordings of modern groups (such as Northern Harmony, Village Harmony and similar)are also available. You could try having a look at the UK Shape Note organisation's website for further information as well (which will probably provide you with links/details of merchandise etc), or the website for Northern Harmony, who sell their own merchandise over the web (although a large number of their CDs also include Balkan, African and other types of music in addition to Shape Note.
