One such group was The Sweet Comfort Band. Check out the musicianship (not the theology) in this clip — the song starts at about two minutes:
It does remind me of the story you've all heard, of the preacher who had a word with someone who was going to sing in the church service."I'll make you a deal," the preacher said. "I won't try to sing, and you don't try to preach."
Back in the '70's Christian rock was particularly new, and I think partly out of feeling apologetic for being rockers, many bands made an effort to preach and evangelize in-between songs. I don't mean to say that condescendingly. You kids won't know this, but Christian rock was a big thing, and it was rather suspect.
When I was first saved, my first regular pastor suggested that I shouldn't listen to rock anymore. So I didn't; threw out all my Chicago (snif!), stopped humming and whistling. Then I heard Bill Gothard go on about how melody appealed to the spirit, harmony to the soul — and rhythm to the flesh!
Next thing I remember is hearing the Second Chapter of Acts, when I was in (as I recall) a Logos bookstore in Westwood, SoCal. I literally gasped. The song was "The Devil's Lost Again" (from their With Footnotes album) — and, by jingo, it was rock and roll! I couldn't believe my ears.
Then later I attended a few concerts at the original Calvary Chapel, in Anaheim. They were still meeting in a tent. The concerts were wonderful. They had some amazing bands, including one called Aslan, another called Parable, and another called The Sweet Comfort Band.
Dude, those guys could rock. Well, check out the video. You'll see.
More reminiscences (or at least clips) to come, DV.
