Picking up where "Music of Ireland - Welcome Home" left off, "Music of Ireland - Welcome to America" is the second half of a two-part performance documentary that tells the definitive story of contemporary Irish music. Focusing on the latest and greatest musical exports from the Emerald Isle, the film takes viewers on a trans-Atlantic journey - from Ireland's West Cost to America's heartland - to spotlight renowned Irish artists who have contributed to the continuation of this glorious relationship between country and music. Clannad's Grammy Award-winning Moya Brennan returns as host and conducts intimate interviews to reveal each artist's special relationship with Ireland and America, and how their musical lives have been influenced by it. "Music of Ireland - Welcome to America" features a behind-the-scenes look at the emergence of U2 and the band's development into one of the world's most popular touring acts; the Dublin singer/songwriter scene, featuring Academy Award-winner Glen Hansard of The Swell Season and The Frames, Damien Rice and Damien Dempsey; and Sinead O'Connor's U.S. breakthrough and papal controversy. Other highlights include interviews and vintage performance footage of pop/rock acts The Cranberries, The Corrs, The Script, and Black 47, and the stories behind PBS phenomena "Lord of the Dance" and "Celtic Woman." The documentary also explores Irish music's influence on American culture, as showcased by performers at the Dublin Irish Festival in Dublin, Ohio. Never-before-seen performances, rare footage and archival photographs are also featured, including U2 on RTE's "Late, Late Show" (1980), The Cranberries on RTE's "On the Waterfront" (1991) and The Script on RTE's "Late, Late Show" (2008).
