Before becoming a solo act, Linda Ronstadt was the lead singer of the Stone Poneys, an L.A.-based trio with an acoustic folkish sound and strong original material. The band's focal point and greatest asset was Ronstadt's clear, powerful singing. Originally recording in a coffeehouse folk style not far removed from Peter, Paul and Mary, the group rocked up its sound slightly and scored a Top 20 hit with "Different Drum," written by Mike Nesmith of the Monkees, in 1967. ~ Richie Unterberger
