Richard Thompson, Martin Carthy, Eliza Carthy, Norma Waterson, Martin Simpson, Dick Gaughan, Corey Harris, Bert Jansch, Alvin Youngblood Hart, Eric Bibb, Kate Rusby, John Hiatt, not necessarily in that order! It's interesting to see what I guess are postings from the US (I'm in the UK) as there are many names I have never heard of although I follow music press etc in the UK.
