Our special two-part series on the battles between Van Halen and their two most famous singers concludes with this exploration of the Van Hagar years. Before he joined Van Halen, Sammy Hagar was a journeyman rock howler with a love of fast cars and mind-controlling aliens. In retrospect, most fans prefer the Roth years, but Hagar was at the head of four consecutive no. 1 albums for Van Halen in the late 1980s and early '90s. And he had a true friendship with Eddie Van Halen, until various factors — including the Twister soundtrack — conspired against them. But in their prime, Van Hagar sold millions of albums to listeners hungry for synth-heavy power ballads with excellent guitar solos.
