Fêted by everyone from Jack White to their most obvious antecedents The Drive-By Truckers, the band from the home of Muscle Shoals certainly have all the right-sounding, raw roots ingredients.
The formidable larynx of Brittany Howard carries the soul-storming drive of primetime Tina Turner with the cauterising melodramatics of Janis Joplin; around her is an outfit well versed in Stax and Creedence riffs, slow burn and the slamdown.
There is a snag, however – as retro rebuilders go Britanny and co lack the essential compositional might that has always defined bluesy-inspired greats – from Bob Dylan to Amy Winehouse and from John Fogerty to the aforementioned Jack White.
Impressive-sounding? Certainly, but it will take deeper, more memorable material for them to advance, rather than merely paying homage to the traditions they draw on.
