JigJam’s North American Tour and Studio Work
JigJam recently concluded their North American tour, which included performances at notable festivals such as Whitaker Music Festival, Blissfest, and DelFest. Their growing reputation as a dynamic band was further bolstered by ongoing studio work, as they record new material at Southern Ground Studio in Nashville. This opportunity came after Zac Brown personally invited the band following their appearance at a festival the previous year.
Southern Ground Studio is known for its rich musical history, having hosted artists like Kris Kristofferson, Kacey Musgraves, Dwight Yoakam, and Foo Fighters, placing JigJam among an esteemed group of musicians. The band’s current work at this location signals their rising trajectory within the Americana and bluegrass scenes.

Recent Releases and Upcoming Music
JigJam’s latest single, Running Back To You, has been released across all streaming platforms, showcasing their blend of Irish roots and American bluegrass styles. Fans eagerly anticipate their upcoming live track, Shake These Dreams, scheduled for release on August 15, which promises to capture the band’s high-energy live sound and authentic performances.
The Origins and Impact of JigJam
JigJam emerged as a unique force by marrying traditional Irish music with bluegrass/Americana influences. The band’s origins lie in the rich folk traditions of Offaly and Tipperary, Ireland, reflecting the historical connections between Irish music and American bluegrass. Founding members Jamie McKeogh (lead singer and guitarist) and Daithi Melia (5-string banjo and dobro) were later joined by Gavin Strappe (mandolin and tenor banjo) and, more recently, Kevin Buckley (fiddle), forming an energetic quartet known as iGrass or Irish bluegrass.
Their groundbreaking Grand Ole Opry debut in Nashville took place in March 2023 to a sold-out crowd that gave a standing ovation, a hallmark moment shared with renowned country artists such as Garth Brooks, Trisha Yearwood, Steve Earle, and Lauren Alaina. The band has been praised as
“The best Irish band in bluegrass”
and as
“Ireland’s answer to New Grass Revival,”
illustrating the powerful fusion of heritage and innovation they bring to the genre.
Significance of the Lollapalooza Aftershow and Future Prospects
John C. Reilly’s unexpected participation at the Lollapalooza aftershow highlights the growing crossover appeal of JigJam and Sierra Ferrell’s music, bridging film, bluegrass, and folk audiences alike. This event not only amplified the visibility of JigJam amid their expanding North American presence but also underscored the vibrant energy of the Irish-American bluegrass movement they embody.
As JigJam continues to develop new recordings at a legendary studio and prepare for upcoming releases, their influence is likely to increase within both traditional and contemporary Americana circles. Their success illustrates a dynamic cultural revival and a hopeful vision for the future of bluegrass music globally.
