Celtic Thunder is a popular multigenerational Irish vocal ensemble and stage show combining traditional Irish folk roots with more contemporary sounds. Emerging in 2008, the long-running production has yielded dozens of platinum-selling albums and videos over the years, including Heritage (2011), Voyage (2012), and Homeland (2021). Celtic Thunder has occasionally explored music outside of the folk idiom with forays into Broadway musicals, pop, rock, and holiday standards.
