Multi-international Celtic rockers The Rumjacks are back with their fifth studio album and new secret weapon: introducing new writer/vocalist Mike Rivkees, and Hestia.

The record rips open with “Naysayers,” a snide delivery from Rivkees suggesting an introduction from himself to skeptical fans, and under a magnificent mix. The opener blends quick punk halftime from drummer Pietro Della Sala, before pulling ska chords out of nowhere on the second verse. This sets a precedent for the entire LP, as the band cleverly changes everything up at the mere chance of predictability, and within a challenging genre facing such a test.

That is without missing out on the paddy-rock instrumentation, of course. “Bullhead,” “Hestia,” and “Through These Iron Sights” rely heavily on the mandolins and whistles packed in a classic Rumjacks deep dive, though the sonic quality of Hestia is by far the best of the discography thus far. The sing-along nature of “Sainted Millions,” pop-sensibility of “Tell Me What Happened,” and intimate delivery from Rivkees on “Rhythm of Her Name” continue to spin the wheel of interest, latching onto the recipient for repeat listens, with the latter title bordering Bad Religion “Sorrow” territory.

Side B cranks things up, stuffing “Golden Death” and “Lizzie Borden” into five minutes of energy. “Light in My Shadow” is a spectacular song, with hooks all over the place and brilliant craftsmanship from Rivkees. “Wanderust” and “Athens to the North” steer Hestia to the exit sign, awaiting a reflective ballad in “Motion,” and the obvious closer “Goodnight & Make Mends.”

Replacing a frontman is a difficult task, but the Rumjacks have found a better storyteller, vocal timbre, and creative energy in Mike Rivkees. This is a killer and unique ride for any fan of the paddy-rock genre. Would recommend.
