I've only just heard about the Liverpool Folk and Roots Festival, described as "a celebration of the history, social significance and abiding presence of folk music in Liverpool". Yes, folk music in Liverpool is more than just In My Liverpool Home and Maggie May. The festival runs from 13th to 20th November in several venues, and includes an Irish music night, Chris Wood, Songs of the Sea, an Americana night, and much more. Some interesting nights there.
Full details and tickets are on the festival website. Obviously quite a lot of work has gone into organising this, so I'm surprised I've not heard about it before today. Still, better late than never.
