And we're all loving their sweet sound! Its a very creative blend of modern folksy/bluegrass/jazz....on that particular Sunday they had a banjo, fiddle and a concertina, besides the guitars and piano. I love that it is so interesting, and yet quiet....complex, but sweet...artistic yet worshipful.
If you pop over to their website, you can hear their songs... my top favorites are Come, Thou Long Expected Jesus and O Come O Come Emmanuel, with What Child Is This? and Silent Night a close second and third. :) The arrangements are so beautiful. Rose just commented that the girls' voices sound like angels singing, and I think I'd have to agree! I highly recommend this album!
