This is where we should be headed with church music (h/t Justin Taylor), theologically and musically! Many of my readers probably know about our local
Emu Music and their American counterparts
Sovereign Grace Music. But if you haven't already you should definitely check out
Red Mountain Music (h/t Nick Gross) some of their hymn re-mixes are great. (Another musical resource in this genre is Craig Schwartz's simple but innovate
'Guitar Cords for Hymns'.)
