Recording of Trevor Wishart's Journey into Space. Miscellaneous sound-sources were collected form metal work-shops, toy-shops, builders' yard etc. some of the material for the original source-tapes was group-improvisation on these collected objects, and/or instruments and voices, some very free, others less so, and yet other sections strictly notated. other sound--sources were recorded individually and mixed or edited later in the studio. all these sounds were sorted, selected, pre-edited, and some treated, from this point the process of tape-composition proper could begin, the work involved was editing, mixing, re-editing, re-mixing, and treatments (speed-change, filtering, etc).
