Red Mountain Music have added all the albums in their back catalogue to their home page at bandcamp.
They also have a page at CD Baby, but the bandcamp prices are lower, US$8.00 an album.
These are much cheaper options for Australians than iTunes.
Red Mountain Music is a part of Red Mountain Church, a Presbyterian Church in America congregation whose pastor, Tom Cannon will be remembered by some from his time in Australia.
I think I first heard about them from my friend Scott Kroeger.
Their music largely takes old hymn words and sets them to new tunes. They have gravitated toward lesser known word sets, attempting to bring compositions which have fallen into disuse back to the church.
Well worth a listen.
Here is their 2005 release The Gadsby Project, named for the 19th century Gadsby Hymns, from which the lyrics come.
Head over to bandcamp and check out all eight of their releases.
