Q: Question: How old is the person hired to replace Vai? Passage:Roth hired 19-year-old guitar virtuoso Jason Becker to replace Vai prior to recording his third solo LP, A Little Ain't Enough. A straight-ahead hard rock album produced by Bob Rock (who had just produced Metallica's self-titled album), A Little Ain't Enough achieved RIAA gold status shortly after its January 1991 release. Before starting a support tour for A Little Ain't Enough, Becker was diagnosed with Lou Gehrig's disease, rendering him unable to perform onstage. Guitarist Joe Holmes stood in for Becker during the tour. Later in 1991, Nirvana and grunge rock emerged, altering musical tastes and suddenly making Roth's brand of hard rock seem unfashionable. Roth's band fractured shortly following the tour's completion. With one exception – 1997's well-received DLR Band album, featuring guitarist John 5 and drummer Ray Luzier – until his reconciliation with Van Halen in 2006, Roth would utilize hired-hands and studio musicians on his club and amphitheater solo tours.
