Nearly all of New 7th's Music is spontaneous and unedited. Its members were not professional musicians, just friends getting together for jam sessions. The music was sometimes "New Age", sometimes "Tribal / Ethnic" with emphasis on percussion (a type of performance known as "Gamelon"), and sometimes involving avant-garde or experimental music. They also threw in a bit of rock and roll on occasion. Some recordings were accompanied by live reading of texts, or improvised spoken word. While the musicians of New 7th Music were not professionals, some of them were rather good at improvising, which is an art in itself.
The line-up of the group was continually changing, and not all members could make it to every session. Occasionally there were guest musicians - including Paul Kelday! The 2 constant members were Phil Kelday, who distributed the tapes, and Heather Rolfe, who designed most of the covers.
