In 1910, Solas band leader Seamus Egan's great-great uncle Michael Conway left his home in Co. Mayo, Ireland and boarded a ship for America. He was headed to the copper mines and boxing rings of Butte, Montana, aka Shamrock City (named so for the influx of Irish immigrants). Six years later, at the age of 25 and in a cloud of mystery, Michael was dead at the hands of local police.

Shamrock City as seen through the eyes of Michael, tells the story of the thousands of young men and women who left behind their homes and families for "the Richest Hill on Earth". It reveals their spirit, tenacity and humor, but also the hardships they faced: discrimination, corruption within the mining companies, an unknown and unforgiving land, a system that valued the few over the many. One hundred years later, it's their story, but the struggles of the working class and immigrants are the same. Shamrock City is for those then and now that believe in a better life, and are willing to risk it all for a chance at something more.
