Erm, quick go off the top of my head in no particular order
Hedgehog Song - Incredible String Band
Matty Groves - Fariport Convention
Karmacoma - Massive Attack
Vincent Black Lightning 1952 - Richard Thompson
Blue Bleezin Blind Drunk - Unthanks
Hmm, folky with a bit of triphop - sounds about right - although that Massive Attack number might give my age away...
