The angst-ridden alt-rock that bands like Nirvana popularized in the early-1990s eventually branched off into a softer, more mature sound with such groups as the Goo Goo Dolls. Although they began as raw and rowdy Replacements-style rockers in the late-'80s, Johnny Rzeznik and company hit paydirt a decade later with the pop ballads "Name" and "Iris."
