Australia's Sons of Korah
My wife and I love the music of the Sons of Korah, the Australian band which has set many of the Psalms to modern tunes. What do they sound like? Think of an Australian version of Shane & Shane with more lyrics, more harmonization and more of a 70's rock influence. You can listen to some of their music here and here. I especially like the album Redemption Songs. The band has a "study" page on the website that includes a brief explanation of the Psalms written by the original sons of Korah. One of the bands' founder members, "Matthew Jacoby, has as a doctorate in philosophy/theology from the University of Melbourne, Australia. He teaches often on the spirituality of the psalms and his concise commentaries on the settings of the psalms is a feature that is woven through most concert events."
