In the first section of the dissertation, I draw on live recordings, presented diachronically, to examine how the band developed this approach to improvisation. In the second section, I address the issue of why they developed this approach; in so doing, I move from strictly musical to religious concerns in order to demonstrate the fundamentally spiritual impetus that drove the band to devise and devotedly practice such a radical approach to rock playing, in the process linking their religious motivations with similarly transcendence-focused aspirations of other radical improvisers of the 1960s.enAuthor owns copyright, except where explicitly noted.
