Fact: A little more than a year ago I took guitar lessons for complete beginners. The guy who taught my group was a nice guy who was into a lot of rock and metal stuff, at least so I gathered. One day when I came in he was talking to a fellow student, a middle-aged woman (who works at the local riding school and who has been my instructor there occasionally, this is a small town - she was also the instructor of another girl in the group, who lives next door to one of my [now former] classmate - anyway).
They were discussing bands, and I think they were on the subject of unknown bands. The guitar teacher pointed to his Sinergy T-shirt and said that "this is a good band that nobody has heard of. I like it, especially the first album, because a friend of mine was one of the guitarists for that one."
I then told him I had heard the name Sinergy mentioned before, although not the music, but he still seemed fairly pleased that they had at least been mentioned somewhere.
