Great irish-punk band from Hungary.
The madly hopping flautist, PJ pulled up a brand new group called Firkin in the summer of 2008. The band injects unadulterated, energetic Irish punk into the veins of the present day musical circulation.
"When Firkin blasts into the strings, the spark of Celtic party cracks. The audience leaves the ground again and again. 100 times, 1000 times. Sounds good? It will!! Fire!" (Unit Magazine)
