Of rock 'n roll's many princes of darkness, American Music Club singer Mark Eitzel has the market cornered on barroom laments. Family, love, and politics are all fair game in Eitzel's somber verses, as his band's eclectic folk-rock arrangements shore up his bleaker visions. AMC first emerged in San Francisco in the mid-'80s with albums like The Restless Stranger and California, and though they never shot for mainstream success, they developed a dedicated following on the strength of their old-fashioned integrity. Eitzel and Co. returned from a ten-year hiatus with 2004's Love Songs for Patriots, and tonight, AMC hit up the Echo alongside Violent Femmes singer Gordon Gano.
