Insomnia was recorded at the Experimental Television Center in three sessions in March, August, and September of 1984. There was another session in May none of the work of which was used. This came on the heals of Bug Eyed Ramrod. The two pieces used similar methods and both employed the CAT fame buffer (this is prior to building the Jones frame buffer).
Before the Flood is made up of recordings from at least 3 sessions at the Experimental TV Center. Before the Flood is a three part piece, the first movement was recorded in January 1985, the second movement in one or two sessions in February, and the third movement was recorded in March.
