the 60s, as they have been sold to younger listeners, are mostly a lie. the beatles were very popular. but you need to go way, way down the list to get to dylan or mitchell or anything else with any kind of social conscience. the reality is that it was a fringe counter-culture.
but, you've probably never heard of this before, have you? the counter-culture was fringe then, but it became dominant because the fringe had the balls (with all due respect to the women involved) to stand up against the market and wave it's freak flag high. now, the 60s mainstream is lost in obscurity. you wouldn't recognize more than half of the most popular songs of the era, but you'd recognize all kinds of stuff that didn't sell at all.
people complain that the market doesn't respond to a counter-culture anymore. but it never did. building a counter-culture is not a profitable business venture. if it sees a financial reward at all, it's not going to happen for years or decades. it's about changing attitudes.
