The Deadstring Brothers perform a brand of blazing country-rock that will bring to mind the style and swagger of early-70s-era Stones and Faces, with overlapping slashing guitars, meaty licks, and full-throated harmony vocals. They’re a skilled sextet with just the right amount of studied sloppiness and a palpable passion for what they do. There are rockers galore on Silver Mountain, their third release, notably “Ain’t No Hidin’ Love” and “Queen of the Scene,” plus some heart-tugging, tears-in-your-beer ballads like the title tune and “Slow Down,” which sounds as if it should be blaring from some dusty honky-tonk somewhere. There’s good chemistry among the band and their sound is loose and energetic, filled with great slide guitar, pedal steel, Hammond organ, and piano that all add up to a rich and delightfully derivative mix that is best played loud.
