Soundgarden: Next Steps

The Seattle grunge rockers have ventured down myriad musical paths since forming in the mid-'80s. Early cut "Big Dumb Sex" groans and grinds over dirty heavy metal licks, a sound that would get sludgier at the turn of the '90s ("Holy Water") and more melodic on breakthrough Superunknown: "Half" takes a Middle Eastern spin and "4th of July" puts a spotlight on Chris Cornell's devilish howl.
