Mama Rosin might just be the best of the Swiss cajun-zydeco-punks bands. Admittedly, it's a small field, but they'd stand out anywhere. Not only is there energy to burn on this, their third ramshackle release, but there's also a sense of passion for the music, and some real imagination. The opener, "Quinze Jours Passes" uses a regional vocal with wordless signing behind it to re-create a work song, while "Le Two-Step Du Motorcycle" has guitar and accordion over a relentless rhythm in a front porch electric blues jam. They move effortlessly between electric and acoustic instruments, including banjo, and create something that's mixed up, deceptively casual, and quite convincing. Cajun and zydeco are just points on their spectrum, which easily encompasses Louisiana blues, and everything is done with a real punk attitude, and more than a little skill. The loose feel of the disc, especially on tracks like the ecstatic "Move Your Popo," is testament to how far they can take things without falling apart. This is a band with a voice that needs to be played loud -- and often.
