The Grateful Dead formed during the era when bands like The Beatles and The Rolling Stones were dominating the airwaves. "The Beatles were why we turned from a jug band into a rock 'n' roll band," said Bob Weir. "What we saw them doing was impossibly attractive. I couldn't think of anything else more worth doing" Former folk-scene star Bob Dylan had recently put out a couple of records featuring electric instrumentation. Grateful Dead members have said that it was after attending a concert by the touring New York City "folk-rock" band The Lovin' Spoonful that they decided to "go electric" and look for a dirtier sound. Gradually, many of the East-Coast American folk musicians, formerly luminaries of the coffee-house scene, were moving in the electric direction. It was natural for Jerry Garcia and Bob Weir, each of whom had been immersed in the American folk music revival of the late 1950s and early '60s, to be open-minded toward electric guitars. But the new Dead music was also naturally different from bands like Dylan's or the Spoonful, partly because their fellow musician Phil Lesh came out of a schooled classical and electronic music background, while Pigpen was a no-nonsense deep blues lover and drummer Bill Kreutzmann had a jazz and R&B background.
