"Plugging in", the fifth episode of the ten episode series of documentaries, "The History of Rock & Roll", opens with the highly lauded and respected singer-songwriter from Minnesota Bob Dylan as he shocks the folk world with amps in 1965. The series is in full swing by the fifth hour as it examines the give and take musically and lyrically between the politically aware, musically daring of a Dylan and the socially under-motivated predictable music of popsters in the vein of the Beatles. The social change and overall upheaval that America burgeons on in the mid 60's is examined here in a strong and meaningful way.
