Sessions of a soulful Congress

(Published by Planet JH Weekly)Each time The Congress comes through town, their sound grows with a little more soul and a heap of vintage grit. The Southern-influenced, Denver-based trio has developed a patience that often starts slow and groovy only to ascend into Black Keys-esque heaviness. The Congress, 10 p.m. Friday at the Pink Garter Theatre. Sneaky Pete & the Secret Weapons open. $10/advance, $12/day-of-show available at The Rose, Pinky G’s and PinkGarterTheatre.com.
