Marc Broussard has had brushes with bona fide chart success, most notably his collaborations with Sara Bareilles and LeAnn Rimes. Ultimately, though, he's a cult artist, a gifted and agile singer whose deep roots in country-soul and blues make him difficult to package. Even on fairly straight-up numbers like "Only Everything" and "Cruel," Broussard's Louisiana background pushes itself to the fore. At a time when soul (country music, too) sounds decidedly suburban and free of regional flavors, Broussard's pop style feels sticky, sweaty and, most importantly, swampy.
