Renowned for her live shows, k.d. lang is that rare performer who, over 25 years as a major-label artist, has matured before our very ears. She launched her career with a blend of country-rock styling and playfully punk-like attitude. But from the very beginning her bravura singing belied her kitschy cowgirl outfits and spiky hair and anyone listening could hear that she was marked for greatness. Sing it Loud is k.d. lang’s first studio album since 2008’s Watershed. The chemistry between lang and her new band, The Siss Boom Bang, is apparent on Sing it Loud, reflecting the organic, collaborative nature of the sessions. $43 to $73.
