Another smart, untraditional way to use radio’s strengths: CBS Radio’s Jack-FM becomes Stones-FM today in honor of rock n’ roll hall of famers The Rolling Stones, who will take over the airwaves in a special broadcast event in four cities across the country. Stations in Los Angeles (93.1 JACK-FM,) Chicago (104.3 JACK-FM), Dallas (100.3 JACK-FM) and Seattle (96.5 JACK-FM) will feature living musical legends Mick Jagger, Keith Richards, Ron Wood and Charlie Watts hosting the four hours of commercial free Jack-FM music from 3-7pm. The takeover event will coincide with the band’s new big screen release, “Shine A Light,” and includes several songs from the film and soundtrack. “Shine A Light” will be released today in theaters and IMAX, which marks it as the largest North American IMAX release in history.
