Classical: Christmas with Chanticleer - A great mix of some older and less recorded madrigals and carols with a few better known ones sung by one of the best classical all male A'Capella groups with a great female soloist
Folk: Lo, He Came to Us is a great original song with great lyrics, feeling and musical backing. The rest of the EP is not as strong but is still interesting.
Pop: I know it is not a new album but Dawn of Grace is a great CD. If On A Winter's Night is a solid CD, although the single track Soul Cake is my least favorite on it.
Mixed artists: Unsigned Christmas is a project that I have enjoyed this year. The advent calender of songs at Adventskalender has some excellent songs. I have not been able to download all of them because the instructions are often in German.
Have a happy New Year! I will see you next Christmas!
