Chrissie Hynde's smoldering attitude and New Wave pop smarts have exerted a deep influence on both fiery alt-rockers and melodic tunesmiths. The singer's toughness echoes throughout Bikini Kill's raw, riot grrrl punk and PJ Harvey's moody, atmospheric art rock. Another key acolyte is Courtney Barnett, whose punchy, hook-riddled indie pop is shaped by the Pretenders' sassy verve.
