Sheffield is an absolutely brilliant place for singers & musicians (trad and otherwise)!

Folks I am lucky enough to hear sing pretty regularly at sessions include (in alphabetical order; links provided if I could find one easily):
Jess Arrowsmith (of Crucible)
Gav Davenport (also of Crucible)
Paul & Liz Davenport
Kate Green an absolutely stunning singer (all four tracks there are excellent, but I particularly recommend Lazarus and I am Stretched on Your Grave)

Other great singers I get to hear in local singing sessions (yes, really!) every now & then:
Jon Boden
James Fagan
Fay Hield
Nancy Kerr
Brian Peters
Graham & Eileen Pratt
Hugh Waller

BTW, did I mention Sheffield is a brilliant place for trad music?
