I started to search for a lot of that stuff after I got into Pentangle but still haven't REALLY found the right one that can stand up to them. I have some friends who's deep into this stuff who recommended Mellow Candle (who sounded mor4e prog than folk to me and were irish but still, pretty good http://www.youtube.com/watch?v=wDETBXD_DeI&feature=related )and another band who I really dug but I can't remember what the hell they were called. I need to ask again... Anyeway, they were also a bit more proggy so I ahven't found the right balance yet-Steeleye Span does nothing for me and I can't totally get into Fairport Convention for some reason even if they are good. Incredible Stringband are nice but a bit too much Monty Python at times...
