Reading the excellent article on psalm singing below, I wanted to add just two more resources.  The Free Church of Scotland has an excellent edition of the Psalter, combing both the 1650 and the new Sing Psalms which should be available from Free Church Bookshop.   And Geneva College has a superb psalm singing ensemble, New Song, whom my wife and I have had the great pleasure of seeing in action over the last couple of nights.  Info on their cds and tour dates are available from here.  Rev. Boadicea von R, vicar in charge of St Olaf the Sublime and opponent of psalmody, recommended the following to me as an alternative to the outmoded fundamentalist patriarchalism of the old covenant.
