I think I saw a new-school folk band on YouTube. There were half a dozen young people in tight clothes and freaky hair-dos, there were red and blue stagelights, and fake fog was drifting about. The instruments were traditional and the style was hackneyed. (guitars went blangety-blangety throughout.) In other words, it was an imitation of a rock band.

The ratio of males to females was about 5 to 1. (Females will be tolerated better if they can play fiddle, the hardest instrument.)

'Old style' would be a man (occasionally a woman) in plaid shirt with a guitar, talking to you for a bit and then singing a song. Chances are good you can even understand the lyrics.

Big Al, i don't think you have to worry about being called old style.
