  Work Details  
  There were no electronic music studios available to me at the time. My friend Ramon Sender Barayon started a studio in the attic at the San Francisco Conservatory of Music. I made my piece at home using only the tape recorder at seven-and-a-half and three-and-three-quarters ips plus a special feature that allowed me to hand wind the tape in record mode so that I had manual variable speed.2 I discovered this feature through experimentation, as it was not a documented use of the machine. I was improvising with sounds and with the uses of the recorder. I imagined how an improvised passage recorded at high speed would sound at low speed and vice versa. Thus my real-time improvisation added a new layer that involved projecting future modification and manipulation of the tape recorder as an instrument. Since I had no other electronic equipment I recorded through cardboard tubes for filters, put the microphone in the bathtub for reverberation and amplified small vibrating objects on an apple box with a contact microphone. The resulting four-channel piece was called Time Perspectives. The synch was done with two stereo tape recorders. (There were no four channel tape recorders at the time.) Ramon and I lined up the tape in the long halls of the San Francisco Conservatory to get the starting points. This piece is now forty-five years old.
