"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 band the Lovin' Spoonful that they decided to "go electric" and look for a dirtier sound . Jerry Garcia and Bob Weir (each of whom had been immersed in the American folk music revival of the late 1950s and early 1960s), were open - minded to electric guitars . </P>
