Starting off in Ireland today...
Above: "Hugo's Jig" and "Banish Misfortune" performed by Spraoi -- a young band from Sligo -- streamed live from Haragan's Bar, Sligo, in 2010. (For an English translation of the lyrics, go here.)
Below: "Hazeltunes," a sweet video and lovely music from JP Trio, a "Celtic roots funk" group created by three Spraoi veterans: Ted Kelly (banjo and tenor guitar), Jos Kelly (button accordion & keyboards), and Paddy Hazleton (percussion) -- occasionally joined by a fourth, Niamh Farrell (vocals). (Welly boot fans, this one's for you.)
Next, crossing over the Atlantic:
"Lazy John," a recent video by the Sligo Creek Stompers, based the Maryland/DC area. They play a terrific mix of Appalachian Irish, Bluegrass, Old Time, and other American roots music.
And now crossing back over the Atlantic, and back to Sligo, Ireland. (Musical influences, after all, travel both ways.)
Below, the young musicians of Grizzly Dippers cover "James River Blues" by the great American roots bands Old Crow Medicine Show. This is the best way to hear music, in my opinion: out doors, by water or a campfire. Or else in the intimate setting of pub, like the video at the top of this post.
