If Duane Eddy's instrumental hits from the late '50s can sound unduly basic and repetitive (especially when taken all at once), he was vastly influential. Perhaps the most successful instrumental rocker of his time, he may have also been the man most responsible (along with Chuck Berry) for popularizing the electric rock guitar. His distinctively low, twangy riffs could be heard on no less than 15 Top 40 hits between 1958 and 1963. He was also one of the first rock stars to successfully crack the LP market.
