You've reached this place for one of three reasons.....
1. You know what it means, you've been to loads of festivals and you have a deep knowledge of the term, but you want to know what we think it is
If you are in this category, then there is nothing new for you to learn here. The debate can very rapidly get subjective and nobody is much the wiser! Wikipedia is a source for further debate - see link below
2. You think Folk-Rock means a) The Byrds, Dylan goes electric etc in the USA or b) Fairport Convention and Pentangle in the UK.
Well yes it did once but now the term is not that narrow in definition! Although the term is synonymous with those acts from the late sixties in both the USA and the UK (mainly because that genre became extremely popular for a brief period), much has happened in the last 35 years to change that
Let's take a look at some of last year's line-up for example:
Zydecomotion play a dance beat version of Zydeco, music native to Louisiana. Kangaroo Moon are half Australian/half English and use an instrument indigenous to Aborigine culture (the didgeridoo) and mix it with psychedelia, fiddle tunes and trance. Salter Cane play alt.country (derived from the US form of folk-rock) and add a bouzouki! ...and on it goes
3. You don't know at all what the term means and you'd like to know
OK, it is, roughly, any form of music with indigenous elements to a particular culture (the folk bit) built on a strong rhythmical backdrop (the rock bit)
Some would disagree with this broader definition and say it has to be European or American music, but you only have to go out to the summer festivals to realise they're wrong - put it another way, we use the term in this broader sense for sure
Check out this link for Wikipedia's definition (which we think is a bit too narrow)
