Opting to stretch the limits of their naturally dynamic partnership as well as critics' expectations on Smoke Ring Halo, the Wood Brothers have avoided simply mimicking the harmonic structures that aided in the unexpected success of 2006's Ways Not to Lose, in the process creating a toe-tapping collection of tracks that hark to the days of harmonica-driven southern rock, while exploring the duo's soulful side. Quashing assertions that the effort is a side project for the siblings, over their career the outfit has released a steady string of records that give listeners a glimpse into the brothers' creative process. Fortunately, Smoke Ring Halo cements the pair's reputation as masters of soulful folk. From its folk-driven opener 'Mary Anna' to the seductive swagger of 'Stumbled In,' Smoke Ring Halo guides listeners on a tour through the multiple genres that both brothers have explored throughout their individual careers.
