From the back of their 1960's album "In The 20th Century Bag"

"Late last September 20-year-old Mike Curb Of Sidewalk Records vacationed in Bavaria, in the remotest foothills of the Alps along the Austrian frontier. One clear, cold night he had trouble getting to sleep. Rather than toss and turn till morning, he got out of bed, dressed, and set off alone to explore a nearby castle which villagers had told him was haunted.

In that dark and gloomy old structure, one room blazed with light. There, assembled together, Mike found the 18th Century Concepts - ten musicians, in blond periwigs, and dressed in scarlet, lace, and gold, playing with a startlingly modern beat upon instruments two centuries old. Quickly setting up the recording equipment he carries wherever he goes, Mike captured forever on tape the incredible sounds they made.

Before the first edges of dawn crept through the castle windows, Mike snapped the single photograph that appears on this album's front cover. With the click of his shutter, the musicians and their instruments vanished into the crisp Bavarian air. To this day, they've never been seen again!"
