For those headbangers who cruised their El Caminos to the riffs of "Bad Motor Scooter" and "Rock the Nation" in the early 1970s, the name Ronnie Montrose needs no introduction. As leader of the band Montrose—which featured Mill Valley's Sammy Hagar on lead vocals—Ronnie paved the way for such later acts as Van Halen and other '80s hair bands.
This Saturday at the Mill Valley Masonic, the Ronnie Montrose Acoustic Trio will unveil the softer, gentler side to Montrose's power-chord infused repertoire. Also on the bill is Bo Carper, co-founder of San Francisco band New Monsoon. Doors at 7:30; music at 8:30. $15 advance. The Masonic is at 19 Corte Madera Ave. Check out www.woodsmv.com.
