Two hard-rocking but otherwise very different bands, they each became unlikely FM radio stars in the post-grunge era of the mid-'90s. You can still hear Social D's "Ball and Chain" or fast-burning version of "Ring of Fire" on any rock station alongside the Toadies' murderous "Possum Kingdom." They're touring together this spring for a double-header that nicely bridges metal and punk audiences. Mike Ness' remade lineup of his pioneering Southern Californian garage-punk band sounded better than ever at First Ave in 2010 (pictured), and last year's album for Epitaph was pretty ferocious, too. Texas' underrated Toadies splintered into the Burden Brothers for much of the '00s but are back with three-quarters of the heyday lineup.
