Very Interesting responces here. I am just going to answer as the question comes to inportant albums to ME . What they did to me. Different moments in time

PP&M's first album made me want to play folk music.
"Bluebird" on Buffalo Springfield made me have to play clawhammer banjo ..
same for the "Old folks at Home" by Taj Mahal
"Music From Clarence Tom Ashleys" showed me there was an Amazing unmined tradition in the USA so strong and real it had to be honered
"Into the perpla Valley "by Rye Cooder made me have to play slide
" For Pence and Good Ale " ??? something like that . The Watersons made me want to sing
" The Young Tradition " the same
and Everything of Martin Carthy 's has made me want to play the guitar.
"THe complete Robert Johnson ". life changing ...
All have been movers in my life and I would not be the same person if I had not found them ..
This month its "Heart's Delight" from Finest Kind thanks Ian Robb.

All the best , Guy
