Roots of Tom Petty

The Raspberries were an American pop rock band formed in Cleveland, Ohio, in 1970. They had a run of success in the early 1970s music scene with their pop rock sound, which AllMusic later described as featuring "exquisitely crafted melodies and achingly gorgeous harmonies." The members were known for their clean-cut public image and matching suits, which brought them teenybopper attention as well as scorn from some mainstream media outlets as "uncool". The group drew influence from the British Invasion era—especially the Beatles, the Who, the Hollies, and the Small Faces—and its mod sensibility. In both the US and the UK, the Raspberries helped pioneer the power pop music style that took off after the group disbanded. They also have had a following among professional musicians such as Jack Bruce, Ringo Starr, and Courtney Love.
