The Rumjacks are a Celtic punk band formed in Sydney, Australia, in 2008. Blending traditional Irish folk sounds with high-energy punk rock, they have drawn comparisons to bands like The Pogues, Flogging Molly, and Dropkick Murphys. Their music combines elements of rock, punk, folk, and ska, often featuring energetic rhythms, powerful vocals, and traditional instruments like the tin whistle, mandolin, and accordion.
