I just saw this on Google Alerts and thought it was great.  Whiskey Daredevils, a band out of Cleveland, I think, just toured Europe and their last show was opening for Berri Txarrak in Bilbao.  They posted about their last show in Bilbao, which was a while ago in May, on the Cleveland Scene website and their experiences with the crowd and opening for what is a huge band in the Basque Country.  This is a great read!  Sounds like they had a blast, but at the same time the expectations were so big that the guy who did the post, Greg Miller (who I think is the lead singer), describes how he had butterflies for the first time in years and how pumped everyone was.  Like I said, well worth the read.  Not much specifically about the Basque Country, but it is does describe the experiences of a smaller US band touring in Europe and Euskal Herria, which is pretty neat.  And their music is pretty cool too.
