"Rock & roll" was the point of departure for the new music. But well known stars of rock & roll "were being called fifties primitives" by this time. This was the period when "rock" was differentiating itself from rock & roll, partly due to the upshot of the British Invasion. Among these British acts, according to music journalist Chris Smith, writing in his book on the most influential albums in American popular music, the Beatles inspired the emergence of the San Francisco psychedelic scene following their incorporation of folk rock on the 1965 album "Rubber Soul", which reflected the reciprocal influences shared between the group and Bob Dylan. San Francisco historian Charles Perry recalled that in Haight-Ashbury, "You could party hop all night and hear nothing but "Rubber Soul"", and that "More than ever the Beatles were the soundtrack of the Haight-Ashbury, Berkeley and the whole circuit." In San Francisco, musical influences came in from not only London, Liverpool and Manchester, but also included the bi-coastal American folk music revival of the 1950s and 1960s, the Chicago electric blues scene, the soul music scenes in Detroit, Memphis, and Muscle Shoals, jazz styles of various eras and regions. A number of key San Francisco rock musicians of the era cited John Coltrane and his circle of leading-edge jazz musicians as important influences.
