If you are looking for a stellar new setting of Martin Luther's hymn, look no further than this mighty rendition for choir, congregation, brass and organ.  Everything about this hymn setting is glorious:  including harmonizations by Mendelssohn and Hassler, Luther's original melodic rhythms and a descant on the final verse that will positively raise the rafters.  This is the quintessential setting for Reformation Sunday, but is glorious on any festive occasion.
