Psychedelic music is a fascinating yet under-researched field of study. This thought-provoking collection offers a broad introduction to the fi eld of psychedelic music studies, bringing together scholarly work on psychedelic music in genres like rock, folk, electronic dance music and pop. Through an expanded purview on psychedelic music, an emerging trend in research, the collection affords students and academics alike an introduction to a rich, multi-faceted field. The contributing authors explore a range of different facets of musical psychedelia: its transgressive and transcendent aspects, its foregrounding of timbre and texture, the way it changes our perception of time, its influence on “non-psychedelic” music, key composition and production techniques that composers and musicians use in its creation, how it is mediated by different places and spaces, and the interplay between psychedelic visual and sonic aesthetics. This interdisciplinary work reveals both commonalities in musical psychedelic experiences and the contestation inherent in a fi eld of study that juxtaposes music of different genres and eras with a variety of theoretical approaches and methodologies. In broadening the scope of psychedelic music research, the collection not only makes for varied and absorbing reading on the subject level but also stimulates reflexive thought about interdisciplinary research.
