I need help (like that's news)

[Forkboy]

A few months back on PBS I watched these two guys playing acoustic guitar like I've never seen before.They had a band with them,but it was mostly just these two guys trading back and forth.It had a Eastern European feel to it (to my damaged ears,anyways),and seemed rooted in old traditional songs.I wrote the name of them down but cannot find it anywhere.I scoured the PBS website for over an hour trying to find any info,but alas,there was nada,zilch,zero.

So,even though my details are skimpier than a Nicole Richie dinner menu,can anyone think of anything like that? It's killing me not knowing this.I need (yes,NEED) to hear that again. :)
