Brian Hopper (born 3 January 1943) is an English guitarist and saxophonist.
With Hugh, he was a member in the early Canterbury scene band Wilde Flowers.
After guesting on saxophone during the sessions for the follow-up album Volume Two in early 1969, he joined Soft Machine full-time for five months from May to October 1969.
The death of two bandmates in the early 1970s discouraged Hopper from pursuing a proper career in music, so he went into agricultural crop protection research and development instead.
[1] Only in the latter part of the 1990s, did Hopper re-emerge as an artist of contemporary as well as historical significance.
