Boasting an enviable lineage -- two sons of Memphis producer Jim Dickinson (Big Star, the Replacements), one son of bluesman R.L. Burnside -- North Mississippi Allstars aim to put a new spin on Southern rock. Their third album, Polaris, is a bluesier -- and more laid-back -- take than that of fellow revivalists Kings of Leon, and when it works, as on the strings-laden ''One to Grow On'' (featuring guest vox from Oasis' Noel Gallagher), ''Polaris'' bears serious fruit.
