In the fourth episode of Watch the Sound With Mark Ronson on Apple TV+, Oscar- and Grammy-winning producer and artist Mark Ronson celebrates the innovators and outsiders who harnessed the power of synthesizers, bringing attention to the unknown but essential women behind their inception and use in music. “Synthesizers can make sounds and patterns never before heard,” Ronson explains in the show. “And most importantly, they can convert a musician with no formal training into a sonic wizard.” Check out these songs by artists including The Beatles, Tame Impala, and Duran Duran that took synthesizers to new levels.
