by Stephen Thomas ErlewineAlthough the title wouldn't indicate it, Your Filthy Little Mouth was a retreat from the thundering hard rock of A Little Ain't Enough. David Lee Roth kept some of the pile-driving guitar riffs that always gave his records a foundation, but he added a smoother pop sensibility, along with self-consciously clever lyrics in an attempt to become a mature hard rocker for all aging yuppies. It didn't work, either commercially or artistically, since most of the songs didn't have enough hooks to make them memorable.
